mac80211: Fix robust management frame handling (MFP)

Commit e34e09401ee9888dd662b2fca5d607794a56daf2 incorrectly removed
use of ieee80211_has_protected() from the management frame case and in
practice, made this validation drop all Action frames when MFP is
enabled. This should have only been done for frames with Protected
field set to zero.

mac80211: Fix dropping of unprotected robust multicast frames

When selecting the RX key for group-addressed robust management
frames, we do not actually select any BIP key if the frame is
unprotected (since we cannot find the key index from MMIE). This
results in the drop_unencrypted check in failing to drop the frame. It
is enough to verify that we have a STA entry for the transmitter and
that MFP is enabled for that STA; we do not need to check rx->key
here. This fixes BIP processing for unprotected, group-addressed,

BIP (part of IEEE 802.11w) is only supposed to be used with

should not break frames completed in most cases, there is no point in
doing this. Fix key selection to pick the default management key only

mac80211: Send deauth/disassoc prior to dropping STA entry

When management frame protection (IEEE 802.11w) is used, the
deauthentication and disassociation frames must be protected whenever
the encryption keys are configured. We were removing the STA entry and
with it, the keys, just before actually sending out these frames which
meant that the frames went out unprotected. The AP will drop them in
such a case. Fix this by reordering the operations a bit so that

wl1271: Fix msleep() delay while waiting for completion

After last transmission, the device goes to sleep earlier
than the configured dynamic power save timeout. If timeout
is set to 400ms, device enters into sleep mode at around
330ms since from last TX.

This patch removes the msleep(1), which causes the delay
after ELP wakeup. Replaced with udelay(10), the variation
is around 7-10ms.
