This series contains updates for mlx5e netdevice driver with one subject,
DSCP to priority mapping, in the first patch Huy adds the needed API in
dcbnl, the second patch adds the needed mlx5 core capability bits for the
feature, and all other patches are mlx5e (netdev) only changes to add
support for the feature.
From: Huy Nguyen
Dscp to priority mapping for Ethernet packet:
These patches enable differentiated services code point (dscp) to
priority mapping for Ethernet packet. Once this feature is
enabled, the packet is routed to the corresponding priority based on its
dscp. User can combine this feature with priority flow control (pfc)
feature to have priority flow control based on the dscp.
Firmware interface:
Mellanox firmware provides two control knobs for this feature:
QPTS register allow changing the trust state between dscp and
pcp mode. The default is pcp mode. Once in dscp mode, firmware will
route the packet based on its dscp value if the dscp field exists.
QPDPM register allow mapping a specific dscp (0 to 63) to a
specific priority (0 to 7). By default, all the dscps are mapped to
priority zero.
Software interface:
This feature is controlled via application priority TLV. IEEE
specification P802.1Qcd/D2.1 defines priority selector id 5 for
application priority TLV. This APP TLV selector defines DSCP to priority
map. This APP TLV can be sent by the switch or can be set locally using
software such as lldptool. In mlx5 drivers, we add the support for net
dcb's getapp and setapp call back. Mlx5 driver only handles the selector
id 5 application entry (dscp application priority application entry).
If user sends multiple dscp to priority APP TLV entries on the same
dscp, the last sent one will take effect. All the previous sent will be
deleted.
This attribute combined with pfc attribute allows advanced user to
fine tune the qos setting for specific priority queue. For example,
user can give dedicated buffer for one or more priorities or user
can give large buffer to certain priorities.
The dcb buffer configuration will be controlled by lldptool.
>> lldptool -T -i eth2 -V BUFFER prio 0,2,5,7,1,2,3,6
maps priorities 0,1,2,3,4,5,6,7 to receive buffer 0,2,5,7,1,2,3,6
>> lldptool -T -i eth2 -V BUFFER size 87296,87296,0,87296,0,0,0,0
sets receive buffer size for buffer 0,1,2,3,4,5,6,7 respectively
After discussion on mailing list with Jakub, Jiri, Ido and John, we agreed to
choose dcbnl over devlink interface since this feature is intended to set
port attributes which are governed by the netdev instance of that port, where
devlink API is more suitable for global ASIC configurations.
The firmware trust state (in QPTS register) is changed based on the
number of dscp to priority application entries. When the first dscp to
priority application entry is added by the user, the trust state is
changed to dscp. When the last dscp to priority application entry is
deleted by the user, the trust state is changed to pcp.
When the port is in DSCP trust state, the transmit queue is selected
based on the dscp of the skb.
When the port is in DSCP trust state and vport inline mode is not NONE,
firmware requires mlx5 driver to copy the IP header to the
wqe ethernet segment inline header if the skb has it.
This is done by changing the transmit queue sq's min inline mode to L3.
Note that the min inline mode of sqs that belong to other features
such as xdpsq, icosq are not modified.

In its current state, the driver will handle backing device
login in a loop for a certain number of retries while the
device returns a partial success, indicating that the driver
may need to try again using a smaller number of resources.
The variable it checks to continue retrying may change
over the course of operations, resulting in reallocation
of resources but exits without sending the login attempt.
Guard against this by introducing a boolean variable that
will retain the state indicating that the driver needs to
reattempt login with backing device firmware.

With the supported classification modes [4 tuples based,
udp port based, src-ip based], flows can be classified
to the VFs as well. With this patch, flows can be re-directed
to the requested VF provided in "action" field of command.
Please note that driver doesn't really care about the queue bits
in "action" field for the VFs. Since queue will be still chosen
by FW using RSS hash. [I.e., the classification would be done
according to vport-only]
For examples -
ethtool -N p5p1 flow-type udp4 dst-port 8000 action 0x100000000
ethtool -N p5p1 flow-type tcp4 src-ip 192.16.6.10 action 0x200000000

Currently, driver supports flow classification to PF

This patch enables to configure different flow profiles
[For example - only UDP dest port or src_ip based] on the
adapter so that classification can be done according to
just those fields as well. Although, at a time just one
type of flow configuration is supported due to limited
number of flow profiles available on the device.
For example -
ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2

pull-request: bpf 2018-05-24
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a bug in the original fix to prevent out of bounds speculation when
multiple tail call maps from different branches or calls end up at the
same tail call helper invocation, from Daniel.
2) Two selftest fixes, one in reuseport_bpf_numa where test is skipped in
case of missing numa support and another one to update kernel config to
properly support xdp_meta.sh test, from Anders.
...
Would be great if you have a chance to merge net into net-next after that.
The verifier fix would be needed later as a dependency in bpf-next for
upcomig work there. When you do the merge there's a trivial conflict on
BPF side with 849fa50662 ("bpf/verifier: refine retval R0 state for

The pixel rate, as reported by the V4L2_CID_PIXEL_RATE control, must
include both horizontal and vertical blanking. Both the AFE and HDMI
receiver program it incorrectly:
- The HDMI receiver goes to the trouble of removing blanking to compute
the rate of active pixels. This is easy to fix by removing the
computation and returning the incoming pixel clock rate directly.
- The AFE performs similar calculation, while it should simply return
the fixed pixel rate for analog sources, mandated by the ADV748x to be
14.3180180 MHz.

We have a confusion of two different abstractions in the Common
Code: Physical Link (Port) and Logical Network Interface (Virtual
Interface), and we haven't been properly managing the state of the
intersection of those two abstractions.
On the one hand we have the Physical state of the Link -- up or down --
and on the other we have the logical state of the VI, enabled or not.
{ethN} refers to both the Physical and Logical State. In this case,
ifconfig only affects/interrogates the Logical State of a VI,
and ethtool only deals with the Physical State. And these are different.
So, just because we disable the VI, we don't really want to change the
Physical Link Up/Down state. Thus, the previous hack to set
"lc->link_ok = 0" when we disable a VI is completely incorrect.
Where we get into trouble is where the Physical Link State and the
Logical VI State cross swords. And that happens in
t4_handle_get_port_info() where we need to manage/safe the Physical
Link State, but we also need to know when the Logical VI State has
changed and pass that back up to the OS-dependent Driver routine
t4_os_link_changed() which is concerned about the Logical Interface.
So we enable a VI and that causes Firmware to send us a new Port
Information message, but if none of the Physical Link State
particulars have changed, we don't call t4_os_link_changed().
This fix uses the existing OS Contract APIs for the Common Code to
inform the OS-dependent portion of the Host Driver when the "Link" (really
Logical Network Interface) is "up" or "down". A new API
t4_enable_pi_params() is added which calls t4_enable_vi_params() and,
if that is successful, then calls back to the OS Contract API
t4_os_link_changed() notifying the OS-dependent layer of the
potential Link State change.
