When a small frame is copied completely into the skb->head, the code
doesn't take alignment into account, making mac80211 copy it again
later on architectures that need the alignment. Avoid this by taking
the PAD flag from the device into account when copying.

In DQA mode the check whether to decrement the pending frames
counter relies on the tid status and not on the txq id.
This may result in an inconsistent state of the pending frames
counter in case frame is queued on a non aggregation queue but
with this TID, and will be followed by a failure to remove the
station and later on SYSASSERT 0x3421 when trying to remove the
MAC.
Such frames are for example bar and qos NDPs.
Fix it by aligning the condition of incrementing the counter
with the condition of decrementing it - rely on TID state for
DQA mode.
Also, avoid internal error like this affecting station removal
for DQA mode - since we can know for sure it is an internal
error.

Our 9000 device supports 64 bit DMA address for RX only, and

A few of the static queues are enabled along with the bcast
STA. Make sure they are removed along with it, rather than
waiting for the mac ctxt release.
This is needed because we sometimes have a STA being removed
and then added again (either with the same sta_id or a
different one). If we wait for the mac ctxt release we will
try to allocate the queues again (as this is currently done
in the STA allocation and not in the MAC init) although
they weren't freed, and even if the sta_id of the STA has
changed.

Instead of setting the tx_cmd length in the mvm code, which is
complicated by the fact that DQA may want to temporarily store
the SKB on the side, adjust the length in the PCIe code which
also knows about this since it's responsible for duplicating
all those headers that are account for in this code.
As the PCIe code already relies on the tx_cmd->len field, this
doesn't really introduce any new dependencies.
To make this possible we need to move the memcpy() of the TX
command until after it was updated.
This does even simplify the code though, since the PCIe code
already does a lot of manipulations to build A-MSDUs correctly
and changing the length becomes a simple operation to see how
much was added/removed, rather than predicting it.

We don't really need clear the skb's status area nor store the
dev_cmd into it until we really commit to the frame by handing
it to the transport - defer those operations until just before
we do that.
This doesn't entirely fix the bug with frames not getting sent
out after having been deferred due to DQA, because it doesn't
restore the info->driver_data[0] place that was already set to
zero (or another value) by the A-MSDU logic.

This does not seem to happen any more with gcc-7, but removing the ACCESS_ONCE
seems safe anyway and it avoids a serious issue for some people. I have verified
that with gcc-5.3.1, the object code we get is better in the new version
both with and without CONFIG_KASAN, as we no longer allocate a 1344 byte
stack frame for hns_dsaf_get_regs() but otherwise have practically identical
object code.
With gcc-7.0.0, removing ACCESS_ONCE has no effect, the object code is already
good either way.
This patch is probably not urgent to get into 4.11 as only KASAN=y builds
with certain compilers are affected, but I still think it makes sense to
backport into older kernels.

When for instance a mobile Linux device roams from one access point to
another with both APs sharing the same broadcast domain and a
multicast snooping switch in between:
1) (c) <~~~> (AP1) <--[SSW]--> (AP2)
2) (AP1) <--[SSW]--> (AP2) <~~~> (c)
Then currently IPv6 multicast packets will get lost for (c) until an
MLD Querier sends its next query message. The packet loss occurs
because upon roaming the Linux host so far stayed silent regarding
MLD and the snooping switch will therefore be unaware of the
multicast topology change for a while.
This patch fixes this by always resending MLD reports when an interface
change happens, for instance from NO-CARRIER to CARRIER state.

mlxsw: cleanup neigh handling
Ido says:
This series addresses long standing issues in the mlxsw driver
concerning neighbour reflection. It also prepares the code for follow-up
changes dealing with proper resource cleanup and nexthop reflection.
The first two patches convert the neighbour reflection code to use an
ordered workqueue, to prevent re-ordering of NEIGH_UPDATE events that
may happen following subsequent patches.
The third to fifth patches remove the ndo_neigh_{construct,destroy}
entry points from the driver, thereby relying only on NEIGH_UPDATE
events for neighbour reflection. This simplifies the code considerably.
Last patches are fallout and adjust nits in the code I noticed while
going over it.

We periodically ask the neighbouring system to try and resolve
neighbours that are used for nexthops, but aren't currently resolved.
However, 'nud_state' is protected by the neighbour lock, so we shouldn't
access it without taking it. Instead, we can simply check the
'connected' field of the neighbour entry, which we update upon
NEIGH_UPDATE events.

In commit 18bfb924f000 ("net: introduce default neigh_construct/destroy
ndo calls for L2 upper devices") we added these ndos to stacked devices
such as team and bond, so that calls will be propagated to mlxsw.
However, previous commit removed the reliance on these ndos and no new
users of these ndos have appeared since above mentioned commit. We can
therefore safely remove this dead code.

Up until now we had two interfaces for neighbour related configuration:
ndo_neigh_{construct,destroy} and NEIGH_UPDATE netevents. The ndos were
used to add and remove neighbours from the driver's cache, whereas the
netevent was used to reflect the neighbours into the device's tables.
However, if the NUD state of a neighbour isn't NUD_VALID or if the
neighbour is dead, then there's really no reason for us to keep it
inside our cache. The only exception to this rule are neighbours that
are also used for nexthops, which we periodically refresh to get them
resolved.
We can therefore eliminate the ndo entry point into the driver and
simplify the code, making it similar to the FIB reflection, which is
based solely on events. This also helps us avoid a locking issue, in
which the RIF cache was traversed without proper locking during
insertion into the neigh entry cache.

We currently associate each neighbour entry with a work item, so it's
not possible to have multiple events queued for the same neighbour
entry. However, this is about to be changed so that the neighbour entry
is only resolved when the work item is scheduled.
The above can result in a mismatch between the kernel's and the device's
neighbour table, unless the associated work items are processed in the
order in which they were submitted.
Do that by migrating the NEIGH_UPDATE work items to be processed in the
ordered workqueue which was recently introduced in mlxsw in commit
a3832b31898f ("mlxsw: core: Create an ordered workqueue for FIB
offload").

In addition we lower bound MPWRQ stride by HCA cacheline in mlx5e,
MPWRQ stride should be at least the HCA cacheline, the current default

Modern flexcan IP cores support two RX modes. One is using the 6 fames deep
hardware FIFO, the other is using up to 64 mailboxes (in non FIFO mode). For
now only the HW FIFO mode is activated.
In order to make use of the RX mailboxes the individual RX masking feature has
to be activated, otherwise matching mailboxes are overwritten during the
reception process. This however switches on the individual RX masking, which
uses reg_rximr registers for masking.
This patch activates the individual RX masking feature unconditionally and
initializes the mask registers (reg_rximr) with 0x0 == "don't care", which
switches off any filtering.
