When adding a PASN station, the station is added to the list only

ADD_STA_CMD_API_S ver 12 was added in order to properly support
auxiliary activities in CDB NICs. In the new version we don't need
to allocate an aux station at initialization, instead we add an
aux station only when an auxiliary activity that requires a dedicated Tx
queue is needed. For now the only case we need this kind of activity is
when using hot spot 2.0

As part of changes made to properly support auxiliary activities in CDB
NICs, an aux sta will be added when using hot spot 2.0 and will need
to be removed when roc flow is done.
In order to do so, prepare the roc_done_wk to work synchronously as the
rm_aux_sta is a SYNC command.

Since now all of th iwl_mvm_flush_sta function are using it sync,
removed the flag argument from the function.

If we have only a single RX queue, such as when MSI-X is not
available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our
only queue is the same as the command queue and will be configured as
part of the context info.  Our code was actually trying to send the
command with 0 queues, which caused UMAC assert 0x1D04.

Fix that by not sending the command when we have a single queue.

clang static analysis reports this problem:

sdio.c:2403:3: warning: Attempt to free released memory
        kfree(card->mpa_rx.buf);
        ^~~~~~~~~~~~~~~~~~~~~~~

When mwifiex_init_sdio() fails in its first call to
mwifiex_alloc_sdio_mpa_buffer, it falls back to calling it
again.  If the second alloc of mpa_tx.buf fails, the error
handler will try to free the old, previously freed mpa_rx.buf.
Reviewing the code, it looks like a second double free would
happen with mwifiex_cleanup_sdio().

So set both pointers to NULL when they are freed.

1. Keep the code for the normal (non-error) flow at the lowest
indentation level. And use "goto drop" for all error handling.

2. Replace code that pads short Ethernet frames with a "__skb_pad" call.

3. Change "dev_kfree_skb" to "kfree_skb" in error handling code.
"kfree_skb" is the correct function to call when dropping an skb due to
an error. "dev_kfree_skb", which is an alias of "consume_skb", is for
dropping skbs normally (not due to an error).

bnxt_en: net-next updates.

This series starts off with the usual update of the firmware interface
spec.  A new firmware status bit in the interface will be used in patch
add the infrastructure to read the firmware status very early during
driver probe and this will allow patch #4 to do the recovery if needed.

The rest of the patches add improvements to the current RX reset
logic by localizing the reset to the affected RX ring only and to
reset only if firmware has determined that the RX ring is in permanent
error state.

Currently, the driver will schedule RX ring reset when we get a buffer
error in the RX completion record.  These RX buffer errors can be due
to normal out-of-buffer conditions or a permanent error in the RX
ring.  Because the driver cannot distinguish between these 2
conditions, we assume all these buffer errors require reset.

This is very disruptive when it is just a normal out-of-buffer
condition.  Newer firmware will now monitor the rings for the permanent
failure and will send a notification to the driver when it happens.
This allows the driver to reset only when such a notification is
received.  In environments where we have predominently out-of-buffer
conditions, we now can avoid these unnecessary resets.

There is logic in the RX path to detect unexpected handles in the
RX completion.  We'll print a warning and schedule a reset.  The
next expected handle is then set to 0xffff which is guaranteed to
not match any valid handle.  This will force all remaining packets in
the ring to be discarded before the reset.  There can be hundreds of
these packets remaining in the ring and there is no need to print the
warnings for these forced errors.

On some older chips, it is necessary to do a reset when we get buffer
errors associated with an RX ring.  These buffer errors may become
frequent if the RX ring underruns under heavy traffic.  The current
code does a global reset of all reasources when this happens.  This
works but creates a big disruption of all rings when one RX ring is
having problem.  This patch implements a localized RX ring reset of
just the RX ring having the issue.  All other rings including all
TX rings will not be affected by this single RX ring reset.

Only the older chips prior to the P5 class supports this reset.
Because it is not a global reset, packets may still be arriving
while we are calling firmware to reset that ring.  We need to be
sure that we don't post any buffers during this time while the
ring is undergoing reset.  After firmware completes successfully,
the ring will be in the reset state with no buffers and we can start
filling it with new buffers and posting them.
