From c0e1899bdbd5e997d2256fcc23fc4e3d2bc5f811 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Mon, 21 Jan 2008 11:09:46 +0900 Subject: [PATCH] ath5k: always extend rx timestamp with tsf always extend the rx timestamp with the local TSF, since this information is also needed for proper IBSS merging. this is done in the tasklet for now, maybe has to be moved to the interrupt handler like in madwifi. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf Signed-off-by: John W.
