When the VF LAG is in use, round-robin the TX affinity of channels among
the different ports, if supported by the firmware. Create a set of TISes
per port, while doing round-robin of the channels over the different
sets. Let all SQs of a channel share the same set of TISes.
If lag_tx_port_affinity HCA cap bit is supported, num_lag_ports > 1 and
we aren't the LACP owner (PF in the regular use), assign the affinities,
otherwise use tx_affinity == 0 in TIS context to let the FW assign the
affinities itself. The TISes of the LACP owner are mapped only to the
native physical port.
For VFs, the starting port for round-robin is determined by its vhca_id,
because a VF may have only one channel if attached to a single-core VM.

This warning triggers because we throw away all the CFLAGS and then make
a new set for REALMODE_CFLAGS, so the -Wno-address-of-packed-member we
added in the following commit is not present:
6f303d6053 ("gcc-9: silence 'address-of-packed-member' warning")
The simplest solution for now is to adjust the warning for this version
of CFLAGS as well, but it would definitely make sense to examine whether
REALMODE_CFLAGS could be derived from CFLAGS, so that it picks up changes
in the compiler flags environment automatically.

net: dsa: mv88e6xxx: Peridot/Topaz SERDES changes
this is the fifth version of changes for the Topaz/Peridot family of
switches. The patches apply on net-next.
Changes since v4:
- added Reviewed-by and Tested-by tags on first 2 patches, the others
are changed are affected by changes in patch 3/6, so I did not add
the tags, except for 5/6, which is just macro renaming
- patch 3 was changed: the serdes_get_lane returns 0 on success (lane
was discovered), -ENODEV if not lane is present on the port, and
other error if other error occured. Lane is put into a pointer of
type u8
- patches 4 and 6 were affected by this (error detecting from
serdes_get_lane)
- Andrew's complaint about the two additional parameters
(allow_over_2500 and make_cmode_writable) was addressed, by Vivien's
advice: I put a new method into chip operations structure, named
port_set_cmode_writable. This is called from mv88e6xxx_port_setup_mac
just before port_set_cmode. The method is implemented for Topaz.
The check if cmodes over 2500 should be allowed on given port is now
done in the specific port_set_cmode() that requires it, thus the
allow_over_2500 argument is not needed
Again, tested on Turris Mox with Peridot, Topaz, and Peridot + Topaz.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently we support SERDES on the Topaz family in a limited way: no
IRQs and the cmode is not writable, thus the mode is determined by
strapping pins.
Marvell's examples though show how to make cmode writable on port 5 and
support SGMII autonegotiation. It is done by writing hidden registers,
for which we already have code.
This patch adds support for making the cmode for the SERDES port
writable on the Topaz family, via a new chip operation,
.port_set_cmode_writable, which is called from mv88e6xxx_port_setup_mac
just before .port_set_cmode.
SERDES IRQs are also enabled for Topaz.
Tested on Turris Mox.

are changed not to use the BIT() macro nor bit shifts, since the rest of
the port.h file does not use it.
We also add the support for setting the Block Address field when
operating hidden registers. Marvell's mdio examples for SERDES settings
on Topaz use Block Address 0x7 when reading/writing hidden registers,
and although the specification says that block must be set to 0xf, those
settings are reachable only with Block Address 0x7.

The mv88e6390_serdes_irq_link_sgmii IRQ handler reads the SERDES PHY
status register to determine speed, among other things. If cmode of the
port is set to 2500base-x, though, the PHY still reports 1000 Mbps (the
PHY register itself does not differentiate between 1000 Mbps and 2500
Mbps - it thinks it is running at 1000 Mbps, although clock is 2.5x
faster).
Look at the cmode and set SPEED_2500 if cmode is set to 2500base-x.
Also tell mv88e6xxx_port_setup_mac the PHY interface mode corresponding
to current cmode in terms of phy_interface_t.

Simplify DSA handling of VLAN subinterface offload
Depends on Vivien Didelot's patchset:
https://patchwork.ozlabs.org/project/netdev/list/?series=127197&state=*
This patchset removes a few strange-looking guards for -EOPNOTSUPP in
dsa_slave_vlan_rx_add_vid and dsa_slave_vlan_rx_kill_vid, making that
code path no longer possible.
It also disables the code path for the sja1105 driver, which does
support editing the VLAN table, but not hardware-accelerated VLAN
sub-interfaces, therefore the check in the DSA core would be wrong.
There was no better DSA callback to do this than .port_enable, i.e.
at ndo_open time.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The switch barely supports traffic I/O, and it does that by repurposing
VLANs when there is no bridge that is taking control of them.
Letting DSA declare this netdev feature as supported (see
dsa_slave_create) would mean that VLAN sub-interfaces created on sja1105
switch ports will be hardware offloaded. That means that
net/8021q/vlan_core.c would install the VLAN into the filter tables of
the switch, potentially interfering with the tag_8021q VLANs.
We need to prevent that from happening and not let the 8021q core
offload VLANs to the switch hardware tables. In vlan_filtering=0 modes
of operation, the switch ports can pass through VLAN-tagged frames with
no problem.

When adding a VLAN sub-interface on a DSA slave port, the 8021q core
checks NETIF_F_HW_VLAN_CTAG_FILTER and, if the netdev is capable of
filtering, calls .ndo_vlan_rx_add_vid or .ndo_vlan_rx_kill_vid to
configure the VLAN offloading.
DSA sets this up counter-intuitively: it always advertises this netdev
feature, but the underlying driver may not actually support VLAN table
manipulation. In that case, the DSA core is forced to ignore the error,
because not being able to offload the VLAN is still fine - and should
result in the creation of a non-accelerated VLAN sub-interface.
Change this so that the netdev feature is only advertised for switch
drivers that support VLAN manipulation, instead of checking for
-EOPNOTSUPP at runtime.

After witnessing the discussion in https://lkml.org/lkml/2019/8/14/151
w.r.t. ioctl extensibility, it became clear that such an issue might
prevent that the 3 RSV bits inside the DSA 802.1Q tag might also suffer
the same fate and be useless for further extension.
So clearly specify that the reserved bits should currently be
transmitted as zero and ignored on receive. The DSA tagger already does
this (and has always did), and is the only known user so far (no
Wireshark dissection plugin, etc). So there should be no incompatibility
to speak of.

net: dsa: explicit programmation of VLAN on CPU ports
When a VLAN is programmed on a user port, every switch of the fabric also
program the CPU ports and the DSA links as part of the VLAN. To do that,
DSA makes use of bitmaps to prepare all members of a VLAN.
While this is expected for DSA links which are used as conduit between
interconnected switches, only the dedicated CPU port of the slave must be
programmed, not all CPU ports of the fabric. This may also cause problems in
other corners of DSA such as the tag_8021q.c driver, which needs to program
its ports manually, CPU port included.
We need the dsa_port_vlan_{add,del} functions and its dsa_port_vid_{add,del}
variants to simply trigger the VLAN programmation without any logic in them,
but they may currently skip the operation based on the bridge device state.
This patchset gets rid of the bitmap operations, and moves the bridge device
check as well as the explicit programmation of CPU ports where they belong,
in the slave code.
While at it, clear the VLAN flags before programming a CPU port, as it
doesn't make sense to forward the PVID flag for example for such ports.
Changes in v2: only clear the PVID flag.

When the bridge offloads a VLAN on a slave port, we also need to
program its dedicated CPU port as a member of the VLAN.
Drivers may handle the CPU port's membership as they want. For example,
Marvell as a special "Unmodified" mode to pass frames as is through
such ports.
Even though DSA expects the drivers to handle the CPU port membership,
it does not make sense to program user VLANs as PVID on the CPU port.
This patch clears this flag before programming the CPU port.

DSA currently programs a VLAN on the CPU port implicitly after the
related notifier is received by a switch.
While we still need to do this transparent programmation of the DSA
links in the fabric, programming the CPU port this way may cause
problems in some corners such as the tag_8021q driver.
Because the dedicated CPU port is specific to a slave, make their
programmation explicit a few layers up, in the slave code.
Note that technically, DSA links have a dedicated CPU port as well,
but since they are only used as conduit between interconnected switches
of a fabric, programming them transparently this way is what we want.

The bridge VLANs are not offloaded by dsa_port_vlan_* if the port is
not bridged or if its bridge is not VLAN aware.
This is a good thing but other corners of DSA, such as the tag_8021q
driver, may need to program VLANs regardless the bridge state.
And also because bridge_dev is specific to user ports anyway, move
these checks were it belongs, one layer up in the slave code.

Add dsa_slave_vlan_add and dsa_slave_vlan_del helpers to handle
SWITCHDEV_OBJ_ID_PORT_VLAN switchdev objects. Also copy the
switchdev_obj_port_vlan structure on add since we will modify it in
future patches.

Currently dsa_port_vid_add returns 0 if the switch returns -EOPNOTSUPP.
This function is used in the tag_8021q.c code to offload the PVID of
ports, which would simply not work if .port_vlan_add is not supported
by the underlying switch.
Do not skip -EOPNOTSUPP in dsa_port_vid_add but only when necessary,
that is to say in dsa_slave_vlan_rx_add_vid.

The bitmap operations were introduced to simplify the switch drivers
in the future, since most of them could implement the common VLAN and
MDB operations (add, del, dump) with simple functions taking all target
ports at once, and thus limiting the number of hardware accesses.
Programming an MDB or VLAN this way in a single operation would clearly
simplify the drivers a lot but would require a new get-set interface
in DSA. The usage of such bitmap from the stack also raised concerned
in the past, leading to the dynamic allocation of a new ds->_bitmap
member in the dsa_switch structure. So let's get rid of them for now.
This commit nicely wraps the ds->ops->port_{mdb,vlan}_{prepare,add}
switch operations into new dsa_switch_{mdb,vlan}_{prepare,add}
variants not using any bitmap argument anymore.
New dsa_switch_{mdb,vlan}_match helpers have been introduced to make
clear which local port of a switch must be programmed with the target
object. While the targeted user port is an obvious candidate, the
DSA links must also be programmed, as well as the CPU port for VLANs.
While at it, also remove local variables that are only used once.
