[PATCH] mwl8k: Set hardware flag IEEE80211_HW_AP_LINK_PS
From: Yogesh Ashok Powar <hidden>

This will avoid mac80211 to trigger PS mode for connected station based on the PM bit of incoming frames. AP firmware is capable of handling such frames and buffering TX frames destined to the stations that are in PS mode.
