Adrian Chadd 1375790a15 net80211: add IEEE80211_IS_QOS_NULL()
This will be useful when fixing up the sequence number generation
and checks, as the rules around how sequence numbers are generated
have been clarified in 802.11-2016 and later.  QoS-NULL frames are
explicitly marked as "any sequence number".

But for now, just create a macro and use it in the one place
it's currently being used as a check - ath(4).

* Add IEEE80211_IS_QOS_NULL().
* Change the "will this frame go into the TX block-ack window" check
  in the ath(4) transmit path.  Note this changes the check to be
  more specific, but both paths already had previous checks to ensure
  they're QoS data frames.

Locally tested:

* ath(4), AR9380, STA mode w/ AMPDU TX/RX enabled and negotiated

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
