Events processing requires locking of bus mutex, which is also used by
cfg80211 layer before calling several of cfg80211 callbacks. Since all
cfg80211 callbacks in qtnfmac driver also lock bus mutex, this
potentially may lead to a deadlock.
Do not use bus lock for event processing. Use RTNL lock instead to
serialize events and commands processing threads.

STA does not reconnect to the same AP after disconnect. The reason is
that STA is marked as disconnected in cfg80211 disconnect callback.
This is too early since in this case qtnfmac event handler skips
cfg80211_disconnected call when processing disconnect event from
the card. As a result, wdev is left in an inconsistent state.

Validate new interface combinations using wireless core checks when new
interface is added or when the type of existing interface is modified.
This is performed to make sure that new interface combination is supported
by hardware. As a result, invalid interface combinations are rejected early,
rather than passed to hardware with sometimes unpredictable results.

Update existing code handling configuration of supported interface
combinations. Current implementation is not complete since it does
not report multiple interface combinations which are incompatible
with each other. Instead current implementation packs all the
supported combinations into single entry.
In fact currently qsr10g wireless card supports the following
two distinct interface combinations:
1. STA/repeater: 1 STA and/or 1 AP
{
{ .max = 1, .types = NL80211_IFTYPE_AP},
{ .max = 1, .types = NL80211_IFTYPE_STA},
}
2. AP/mBSS
{
{ .max = 8, .types = NL80211_IFTYPE_AP},
}
The list of supported configuration is reported by firmware during
wireless card bring-up. Communication protocol between firmware
and host has been updated accordingly in order to accommodate passing
multiple interface combination entries.

On 32-bit platforms packet counters are stored in a net_device_stats struct
as unsigned long integers. As a result, after some time of network activity
an overflow takes place in network packet counters. This patch makes use of

Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.

Fix hw queue configuration since mt76x2 devices use a reverse queue
enumeration respect to mac80211 one:
- 0: AC_BE
- 1: AC_BK
- 2: AC_VI
- 3: AC_VO
The issue can be reproduced sending two concurrent flow using
two separate queues:
- VO: 20Mbps UDP traffic
- BE: TCP traffic
In this scenario the UDP traffic will be blocked by the TCP one.

mlx5-updates-2018-01-19
From: Or Gerlitz <ogerlitz@mellanox.com>
=======
First six patches of this series further enhances the mlx5 hairpin support.
The first two patches deal with using different hairpin instances
for flows whose packets have different priorities to align with the port
TX QoS model. The next four patches allow us to do HW spreading
of flows over a set of hairpin pairs using RSS. The last two patches
change the driver to also set the size of the HW hairpin queues.
========
Next four patches from Eran Ben Elisha <eranbe@mellanox.com>:
Add more debug data for TX timeout handling, and further enhance and optimize
TX timeout handling upon lost interrupts, which adds a mechanism for explicitly
polling EQ in case of a TX timeout in order to recover from a lost interrupt.
If this is not the case (no pending EQEs), perform a channels full recovery as
usual.
From Kamal Heib <kamalh@mellanox.com>, Two patches to extend the stats group API
to have an update_stats() callback which will be used to fetch the hardware or
software counters data, this will improve the current API and reduce code
duplication.
From Gal Pressman <galp@mellanox.com>, Last patch, Add likely to the common RX checksum
flow.

Previously it was possible to interrupt processing stats updates because
they were handled in a work queue. Interrupting the stats updates could
lead to a situation where we backup the control message queue. This patch
moves the stats update processing out of the work queue to be processed as
soon as hardware sends a request.

2) support for bpf_get_next_key() for LPM map, from Yonghong.
3) test_verifier now runs loaded programs, from Alexei.
4) xdp cpumap monitoring, from Jesper.
5) variety of tests, cleanups and small x64 JIT optimization, from Daniel.
6) user space can now retrieve HW JITed program, from Jiong.
Note there is a minor conflict between Russell's arm32 JIT fixes

The BPF verifier conflict was some minor contextual issue.
The TUN conflict was less trivial. Cong Wang fixed a memory leak of
tfile->tx_array in 'net'. This is an skb_array. But meanwhile in
net-next tun changed tfile->tx_arry into tfile->tx_ring which is a
ptr_ring.
