If /sbin/bridge-stp is available on the system, bridge tries to execute
it instead of the kernel implementation when starting/stopping STP.
If anything goes wrong with /sbin/bridge-stp, bridge silently falls back
to kernel STP, making hard to debug userspace STP.
This patch adds a br_stp_call_user helper to start/stop userspace STP
and debug errors from the program: abnormal exit status is stored in the
lower byte and normal exit status is stored in higher byte.
Below is a simple example on a kernel with dynamic debug enabled:
# ln -s /bin/false /sbin/bridge-stp
# brctl stp br0 on
br0: failed to start userspace STP (256)
# dmesg
br0: /sbin/bridge-stp exited with code 1
br0: failed to start userspace STP (256)

hw_4addr_pad was added to handle different types of padding
in 4-address rx frame. But this padding is not very specific
to 4-address, it can happen even with three address + ethernet
decap mode. Since the padding information can be obtained
through Rx desc for QCA99X0 and newer chips, this hw_param
is not needed any more.

In QCA99X0 (QCA99X0, QCA9984, QCA9888 and QCA4019) family chips,
hw adds padding at the begining of the rx payload to make L3
header 4-byte aligned. In the chips doing this type of padding,
the number of bytes padded will be indicated through msdu_end:info1.
Define a hw_rx_desc_ops wrapper to retrieve the number of padded
bytes and use this while doing undecap. This should fix padding
related issues with ethernt decap format with QCA99X0, QCA9984,
QCA9888 and QCA4019 hw.

There are slight differences in Rx hw descriptor information
among different chips. So far driver does not use those new
information for any functionalities, but there is one important
information which is available from QCA99X0 onwards to indicate
the number of bytes that hw padded at the begining of the rx
payload and this information is needed to undecap the rx
packet. Add an abstraction for Rx desc to make use of the
new desc information available. The callback that this patch
defines to retrieve the padding bytes will be used in follow-up
patch.

smatch pointed out that the second check of "tdls_auth" was
pointless since if it was true, we returned from the function

handle that inside. This simplifies the control flow here.

Currently the 'aqm' stats in mac80211 only keeps overlimit drop stats,
not CoDel stats. This moves the CoDel stats into the txqi structure to
keep them per txq in order to show them in debugfs.
In addition, the aqm debugfs output is restructured by splitting it up
into three files: One global per phy, one per netdev and one per
station, in the appropriate directories. The files are all called aqm,
and are only created if the driver supports the wake_tx_queue op (rather
than emitting an error on open as previously).

The ability to change the max_rx_aggregation frames is useful
in cases of IOP.
There exist some devices (latest mobile phones and some AP's)
that tend to not respect a BA sessions maximum size (in Kbps).
These devices won't respect the AMPDU size that was negotiated during
association (even though they do respect the maximal number of packets).
This violation is characterized by a valid number of packets in
a single AMPDU. Even so, the total size will exceed the size negotiated
during association.
Eventually, this will cause some undefined behavior, which in turn
causes the hw to drop packets, causing the throughput to plummet.
This patch will make the subframe limitation to be held by each station,
instead of being held only by hw.
