de1ede7ac3 mac80211: make BA session handling independent of STA mode
The aggregation handling isn't dependent on anything related to our
STA-mode implementation, and doesn't need to depend on it for frame
processing. This patch moves the relevant code to ht.c and adds a
hook in rx.c. For now, the relevant action frames are only processed
in STA/IBSS modes, but that's now something we can easily change.

90d7795e15 iwlwifi: fix searching for best rate in new search column
This patch fixes a bug in Rate Scaling. When moving from SISO to MIMO we
need to choose the lowest higher rate, instead of choosing the highest in MIMO.
No doing this can lead to a high packet loss in the highest rate in MIMO,
leading not to move MIMO although lower in MIMO could give a better TPT.

71b35f3abe libertas: clear current command on card removal

9ac19a9084 mac80211: reorder frame code in mlme
This reorders all frame sending functions to be at the top of the

is confusing. When all frame sending is at the top the remainder
of the file is more readable, in my opinion.

24e64622c3 mac80211: stop queues before carrier off
During testing of the disassociation fixes, Tomas noticed that it
was possible to run into a situation where you'd suddenly get a
few "wlan0: dropped frame to <AP> (unauthorized port)" messages
and I found this to be due to the AP's sta_info having been
removed but netif_carrier_off not having removed/stopped traffic
yet. To avoid that, stop the queue for the interface (and avoid
bringing them up when another vif scans when they weren't up.)

This patch makes the MLME cleanly disassociate from the current BSS
when leaving it for a new one. This is not just nicer to the old AP
(we're leaving it, might as well tell it!) but also required for some
drivers that keep track of the station we're associated with, they'd
get confused because they'd think we are associated with two APs.

It also synchronizes between the chain noise alg and the W/A that

restored only after the completion of the algorithm.

In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

were the culprit.

The problem is that ICMP6 routes live in their own world totally
separate from normal ipv6 routes.  So there are all kinds of special
cases throughout the ipv6 code to handle this.

While we should really try to unify all of this stuff somehow,
for the time being let's fix this by purging the ICMP6 routes
that match the device in question during rt6_ifdown().

Otherwise entries stay on the GC todo list forever, even after we free
them.
