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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
