From 5aae2880618471cfa679ca22531b88990bee9bf8 Mon Sep 17 00:00:00 2001 From: Ron Rindjunsky Date: Tue, 25 Dec 2007 17:00:32 +0200 Subject: [PATCH] mac80211: A-MPDU Rx add MLME structures This patch adds the needed structures to describe the Rx aggregation MLME per STA new: - struct tid_ampdu_rx: TID aggregation information (Rx) - struct sta_ampdu_mlme: MLME aggregation information for STA changed: - struct sta_info: ampdu_mlme added to describe A-MPDU MLME per STA, and timer_to_tid added to map timer id into TID Signed-off-by: Ron Rindjunsky Signed-off-by: John W.
