Merge tag 'mac80211-for-davem-2019-04-09' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg says:

====================
Various fixes:
 * iTXQ fixes from Felix
 * tracing fix - increase message length
 * fix SW_CRYPTO_CONTROL enforcement
 * WMM rule handling for regdomain intersection
 * max_interfaces in hwsim - reported by syzbot
 * clear private data in some more commands
 * a clang compiler warning fix

I added a patch with two new (unused) macros for
rate-limited printing to simplify getting the users
into the tree.
