move ath5k_tx_status and ath5k_rx_status structures out of the hardware descriptor since they are not accessed by the hardware at all. they just contain converted information from the hardware descriptor. since they are only used in the rx and tx tasklets there is also no use to keep them for each descriptor. drivers/net/wireless/ath5k/ath5k.h: Changes-licensed-under: ISC drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/debug.c: Changes-licensed-under: GPL drivers/net/wireless/ath5k/debug.h: Changes-licensed-under: GPL drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.
