[RFC PATCH v3 08/12] iwlwifi: dvm - EXT_KEY_ID A-MPDU API update

[Alexander Wetzel <alexander@wetzel-home.de>]

When using Extended Key ID mac80211 drops @IEEE80211_TX_CTL_AMPDU for
the last packet which can be added to a A-MPDU in preparation.

Don't throw a warning and just handle the frame as if
@IEEE80211_TX_CTL_AMPDU would have been set.

I cold not figure out so far how to make sure the card will not mix
A-MPDU frames. Looks like that is handled fully in the HW and I didn't
find any interface to influence it. (It even may work already, I have
some problems to capture A-MPDU frames with A-MPDU information intact
and the topic was pretty low on the list so far. After all it works...)

This patch is therefore basically just using aggregation when it's
enabled and ignores the key border signal from mac80211.
