In dual-emac mode the cpsw driver sends directed packets, that means
that packets go to the directed port, but an ALE lookup is performed
to determine untagged egress only. It means that on tx side no need
to add port bit for ALE mcast entry mask, and basically ALE entry
for port identification is needed only on rx side.
So, add only host port in dual_emac mode as used directed
transmission, and no need in one more port. For single port boards
and switch mode all ports used, as usual, so no changes for them.
Also it simplifies farther changes.
In other words, mcast entries for dual-emac should behave exactly
like unicast. It also can help avoid leaking packets between ports
with same vlan on h/w level if ports could became members of same vid.
So now, for instance, if mcast address 33:33:00:00:00:01 is added then
entries in ALE table:
vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x1
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x1
Instead of:
vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x3
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x5
With the same considerations, set only host port for unregistered
mcast for dual-emac mode in case of IFF_ALLMULTI is set, exactly like
it's done in cpsw_ale_set_allmulti().

In the commit referred to below we added link tolerance as an additional
criteria for declaring broadcast transmission "stale" and resetting the
unicast links to the affected node.
Unfortunately, this 'improvement' introduced two bugs, which each and
one alone cause only limited problems, but combined lead to seemingly
stochastic unicast link resets, depending on the amount of broadcast
traffic transmitted.
The first issue, a missing initialization of the 'tolerance' field of
the receiver broadcast link, was recently fixed by commit 047491ea33
("tipc: set link tolerance correctly in broadcast link").
Ths second issue, where we omit to reset the 'stale_cnt' field of
the same link after a 'stale' period is over, leads to this counter
accumulating over time, and in the absence of the 'tolerance' criteria
leads to the above described symptoms. This commit adds the missing
initialization.

veth: XDP stats improvement
ndo_xdp_xmit in veth did not update packet counters as described in [1].
Also, current implementation only updates counters on tx side so rx side
events like XDP_DROP were not collected.
This series implements the missing accounting as well as support for
ethtool per-queue stats in veth.
Patch 1: Update drop counter in ndo_xdp_xmit.
Patch 2: Update packet and byte counters for all XDP path, and drop
counter on XDP_DROP.
Patch 3: Support per-queue ethtool stats for XDP counters.
Note that counters are maintained on per-queue basis for XDP but not
otherwise (per-cpu and atomic as before). This is because 1) tx path in
veth is essentially lockless so we cannot update per-queue stats on tx,
and 2) rx path is net core routine (process_backlog) which cannot update
per-queue based stats when XDP is disabled. On the other hand there are
real rxqs and napi handlers for veth XDP, so update per-queue stats on
rx for XDP packets, and use them to calculate tx counters as well,
contrary to the existing non-XDP counters.

IPoIB netlink support and mlx5e pre-allocated netdevice initialization

2) Reworks IPoIB initialization to use the two step rdma_netdev
creation.
From Feras and Saeed, mlx5e netdev layer refactoring to allow accepting
pre-allocated netdevs:
3) Adds support to initialize/cleanup netdevs that are not created
by mlx5 driver.
4) Change mlx5e netdevice layer to accept the pre-allocated netdevice
queue number.
5) Initialize mlx5e generic structures in one place to be used for all
netdevs types NIC/representors/IPoIB (both mlx5 allocated and
pre-allocted).

Saeed Mahameed says:
====================
mlx5e-updates-2018-10-10
IPoIB netlink support and mlx5e pre-allocated netdevice initialization
IP link was broken due to the changes in IPoIB for the rdma_netdev
support after commit cd565b4b51
("IB/IPoIB: Support acceleration options callbacks").
This patchset fixes IPoIB pkey creation and removal using rtnetlink by
adding support in both IPoIB ULP layer and mlx5 layer:
From Jason and Denis:
1) Introduces changes in the RDMA netdev code in order to
allow allocation of the netdev to be done by the rtnl netdev code.
2) Reworks IPoIB initialization to use the two step rdma_netdev
creation.
From Feras and Saeed, mlx5e netdev layer refactoring to allow accepting
pre-allocated netdevs:
3) Adds support to initialize/cleanup netdevs that are not created
by mlx5 driver.
4) Change mlx5e netdevice layer to accept the pre-allocated netdevice
queue number.
5) Initialize mlx5e generic structures in one place to be used for all
netdevs types NIC/representors/IPoIB (both mlx5 allocated and
pre-allocted).

Similarly to what has been done in 8b4c3cdd9d ("net: sched: Add policy
validation for tc attributes"), fix classifier code to add validation of
TCA_CHAIN and TCA_KIND netlink attributes.
tested with:
# ./tdc.py -c filter
v2: Let sch_api and cls_api share nla_policy they have in common, thanks
to David Ahern.
v3: Avoid EXPORT_SYMBOL(), as validation of those attributes is not done
by TC modules, thanks to Cong Wang.
While at it, restore the 'Delete / get qdisc' comment to its orginal
position, just above tc_get_qdisc() function prototype.
Fixes: 5bc1701881 ("net: sched: introduce multichain support for filters")
