Subject: [PATCH] mac80211_hwsim: add power save support
Git-commit: 01afc6fedffb519a98322074c645baa2b0fa041f
Patch-mainline: v5.7-rc1
References: jsc#SLE-13430
Advertise the correct flags to mac80211 to indicate PS
trigger frames and frame buffering should be handled by
mac80211. This means mac80211_hwsim will now also have to
release buffered multicast frames after a (DTIM) beacon.
Leave STA power save disabled by default since it causes
several p2p, scanning, and rrm hostap tests to fail.
