rndis_wlan: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

802.1d defines 0,3 for BE and 1,2 for BK. In pcie dongles, 0 & 3 are
mapped to 0 and 1,2 are mapped to 1. This change corrects this mapping,
so that BE & BK are given access precedence accordingly by pcie dongles.

brcmfmac: map 802.1d priority to precedence level based on AP WMM params
In WLAN, priority among various access categories of traffic is
always set by the AP using WMM parameters and this may not always
follow the standard 802.1d priority.
In this change, priority is adjusted based on the AP WMM params
received as part of the Assoc Response and the same is later used
to map the priority of all incoming traffic.
In a specific scenario where EDCA parameters are configured to be same
for all ACs, use the default FW priority definition to avoid queuing
packets of all ACs to the same priority queue.
This change fixes the following 802.11 certification tests:
* 11n - 5.2.31 ACM Bit Conformance test
* 11n - 5.2.32 AC Parameter Modification test
* 11ac - 5.2.33 TXOP Limit test

====================
bonding: report transmit status to callers
First patches cleanup netpoll, and make sure it provides tx status to its users.
Last patch changes bonding to not pretend packets were sent without error.
By providing more accurate status, TCP stack can avoid adding more
packets if the slave qdisc is already full.
This came while testing latest horizon feature in sch_fq, with
very low pacing rate flows, but should benefit hosts under stress.

bonding: propagate transmit status
Currently, bonding always returns NETDEV_TX_OK to its caller.
It is worth trying to be more accurate : TCP for instance
can have different recovery strategies if it can have more
precise status, if packet was dropped by slave qdisc.
This is especially important when host is under stress.
