mac80211_hwsim: Add support for client PS mode
This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be used to force a simulated radio into power save mode. Following values can be written into this file to change PS mode: 0 = power save disabled (constantly awake) 1 = power save enabled (drop all frames; do not send PS-Poll) 2 = power save enabled (send PS-Poll frames automatically to receive buffered unicast frames); not yet fully implemented 3 = manual PS-Poll trigger (send a single PS-Poll frame) Two different behavior for power save mode processing can be tested: - move between modes 1 and 0 (i.e., receive all buffered frames at a time) - move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps' debugfs file) to fetch power save buffered frames one at a time Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but eventually, it should take a look at TIM IE and send PS-Poll if a traffic bit is set for our AID.
