Merge tag 'mac80211-for-davem-2018-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Various fixes across the tree, the shortlog basically says it all:
cfg80211: fix cfg80211_beacon_dup
-> old bug in this code
cfg80211: clear wep keys after disconnection
-> certain ways of disconnecting left the keys
mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4
-> alignment issues with using 14 bytes
mac80211: Do not disconnect on invalid operating class
-> if the AP has a bogus operating class, let it be
mac80211: Fix sending ADDBA response for an ongoing session
-> don't send the same frame twice
cfg80211: use only 1Mbps for basic rates in mesh
-> interop issue with old versions of our code
mac80211_hwsim: don't use WQ_MEM_RECLAIM
-> it causes splats because it flushes work on a non-reclaim WQ
regulatory: add NUL to request alpha2
-> nla_put_string() issue from Kees
mac80211: mesh: fix wrong mesh TTL offset calculation
-> protocol issue
mac80211: fix a possible leak of station stats
-> error path might leak memory
mac80211: fix calling sleeping function in atomic context
-> percpu allocations need to be made with gfp flags
