A follow-up patch enables emitting VLAN notifications for the bridge CPU
port in addition to the existing slave port notifications. These
notifications have orig_dev set to the bridge in question.
Because there's no specific support for these VLANs, just ignore the
notifications to maintain the current behavior.

Driver switches vif sta_state into QTNF_STA_CONNECTING when cfg80211
core initiates connect procedure. Further this state is changed either
to QTNF_STA_CONNECTED or to QTNF_STA_DISCONNECTED by BSS_JOIN and
BSS_LEAVE events from firmware. However it is possible that no such
events will be sent by firmware, e.g. if EAPOL timed out.
In this case vif sta_mode will remain in QTNF_STA_CONNECTING state and
all subsequent connection attempts will fail with -EBUSY error code.
Fix this by perfroming STA state transition from QTNF_STA_CONNECTING
to QTNF_STA_DISCONNECTED in cfg80211 disconnect callback.
No need to rely upon firmware events in this case.

Driver uses statically allocated wdev structures for each virtual
interface. However wdev structure is not properly cleaned up between
its uses. As a result, various bugs appear when userspace tools
like hostapd were not gracefully stopped.
In particular, this commit fixes the following issue:
- start hostapd with more than 2 mBSS
- kill hostapd using SIGKILL
- start again hostapd with more than 2 mBSS
However only two mBSS entities will be started: primary
and the last BSS listed in hostapd config.

While compile-testing on arm64 with gcc-8.1, I ran into a build diagnostic:
drivers/net/ethernet/freescale/fec_main.c: In function 'fec_probe':
drivers/net/ethernet/freescale/fec_main.c:3517:25: error: '%d' directive writing between 1 and 10 bytes into a region of size 5 [-Werror=format-overflow=]

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It appears this has never shown on ppc32 or arm32 for an unknown reason, but
now gcc fails to identify that the 'irq_cnt' loop index has an upper bound
of 3, and instead uses a bogus range.
To work around the warning, this changes the sprintf to snprintf with the
correct buffer length.

Initially in this code, the race didn't matter since it didn't
do anything. Latest with the commit I marked this as fixing it
started to matter as something got done here that needed other
data that got freed as soon as the queue notification wait was
returning.
In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA
event was sent to all queues, but processing the last event we
returned from iwl_mvm_sync_rx_queues_internal() and then from
iwl_mvm_free_reorder() and continued some processing before
wl_mvm_del_ba() was even invoked on the other CPU. Thus, when
the latter finally ran, it found that mvm->baid_map[baid] was
no longer valid.
Correct the race by moving the counter decrement and wake_up()
to be done only after all the per-event processing completed.
Note that in the commit I marked as being fixed the wake_up()
didn't exist yet (and the code was otherwise problematic) but
this particular problem already existed in a way.

Make sure the rx_allocator worker is canceled before running the
rx_init routine. rx_init frees and re-allocates all rxb's pages. The
rx_allocator worker also allocates pages for the used rxb's. Running
rx_init and rx_allocator simultaniously causes a kernel panic. Fix
that by canceling the work in rx_init.

Our hardware has a limited amount of buffer descriptors
for each Tx packet. Because of that, there is a short
piece of code that makes sure that that we don't push too
many subframes in an A-MSDU because of subframes needs 2
buffer descriptors. This code also takes into account the
number of fragment of the skb since we also need a buffer
descriptor for each fragment in the skb.
This piece of code though didn't check that the resulting
number of subframes wasn't 0.
A user reported that using NFS client, he could get skbs
that are so fragmented that the code mentioned above
returned 0 for the number of subframes making
skb_gso_segment fail and subconsequently iwlwifi would WARN.
Fix this by make sure that num_subframes is at least 1.

In some cases we may get from FW errored frames with
UNKNOWN security type.
This may happen in unsecured aggregation flow, where
the first packet had a CRC error in the WEP bit, which
was followed by a failure to decrypt and was dropped.
The next frames in the aggregation "inherit" the bad metadata
of the first packet.
Make sure to drop such frames since RADA and other offloads
will not operate correctly which may have unexpected results.
In case of AP it also causes to TX AMSDU frames to the peers,
resulting with assert 0x104B.

So far, the PCI BAR0 register is used for triggering FW reset. However,
that is a legacy attitude and it is recommended to use MRSR to perform
reset instead. So do that. Move the reset into init() function as
the cmd interface needs to be used. With that, IRQ initialization needs
to be moved as well. As a side effect, the reset move simplifies
the devlink reload flow.

There is an exception in command interface processing in case the MRSR
register is written to. The register triggers FW reset and during the
reset FW returns an error. So handle this by ignoring this error while
writing to MRSR register.

VLAN 1 is internally used for untagged traffic. Prevent creation of
explicit netdevice for that VLAN, because that currently isn't supported
and leads to the NULL pointer dereference cited below.
Fix by preventing creation of VLAN devices with VID of 1 over mlxsw
devices or LAG devices that involve mlxsw devices.

With CONFIG_TLS=m and MLX5_CORE_EN=y, we get a link failure:
drivers/net/ethernet/mellanox/mlx5/core/en_accel/tls_rxtx.o: In function `mlx5e_tls_handle_ooo':
tls_rxtx.c:(.text+0x24c): undefined reference to `tls_get_record'

tls_rxtx.c:(.text+0x9a8): undefined reference to `tls_device_sk_destruct'
This narrows down the dependency to only allow the configurations
that will actually work. The existing dependency on TLS_DEVICE is
not sufficient here since MLX5_EN_TLS is a 'bool' symbol.
