[PATCH 1/4] mac80211: Move IEEE80211_TX_CTL_PS_RESPONSE
From: Sujith Manoharan <hidden>
Date: 2014-12-10 15:54:13
Subsystem:
atheros ath generic utilities, mac80211, qualcomm atheros ath9k wireless driver, the rest · Maintainers:
Jeff Johnson, Johannes Berg, Toke Høiland-Jørgensen, Linus Torvalds
From: Sujith Manoharan <redacted> Move IEEE80211_TX_CTL_PS_RESPONSE to info->control.flags since this is used only in the TX path (by ath9k). This frees up a bit which can be used for other purposes.
