Dave, Here are a few more intended for 2.6.29. The ath5k one is already in -next, but it turns-out to affect 2.6.29 as well. The two zd1211rw ones are one-liners that enable new hardware for that driver. The iwlwifi patch corrects a problem (introduced by the previous iwlwifi fix) that disables the iwlwifi devices after suspend/resume. It will conflict with what is already in -next -- just take the hunks that are already in -next and ignore the hunks introduced here. Please let me know if there are problems! Thanks, John --- Individual patches are available here: http://www.kernel.org/pub/linux/kernel/people/linville/wireless-2.6/ --- The following changes since commit 7b7a799d664a46eec6cb7de200c90f40730497a7: Meelis Roos (1): sunhme: Fix Quattro HME irq registration on proble failures are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git master Bob Copeland (1): ath5k: fix bf->skb==NULL panic in ath5k_tasklet_rx Hin-Tak Leung (2): zd1211rw: adding 0ace:0xa211 as a ZD1211 device zd1211rw: treat MAXIM_NEW_RF(0x08) as UW2453_RF(0x09) for TP-Link WN322/422G Johannes Berg (1): mac80211: restrict to AP in outgoing interface heuristic Reinette Chatre (1): iwlwifi: fix suspend/resume and its usage of pci saved state drivers/net/wireless/ath5k/base.c | 85 +++++++++++++++++---------- drivers/net/wireless/iwlwifi/iwl-agn.c | 15 ++++- drivers/net/wireless/iwlwifi/iwl3945-base.c | 15 ++++- drivers/net/wireless/zd1211rw/zd_rf.c | 1 + drivers/net/wireless/zd1211rw/zd_usb.c | 1 + net/mac80211/tx.c | 2 + 6 files changed, 83 insertions(+), 36 deletions(-) diff --git a/drivers/net/wireless/ath5k/base.c b/drivers/net/wireless/ath5k/base.c index a533ed6..1d77ee9 100644 --- a/drivers/net/wireless/ath5k/base.c +++ b/drivers/net/wireless/ath5k/base.c @@ -1098,6 +1098,42 @@ ath5k_hw_to_driver_rix(struct ath5k_softc *sc, int hw_rix) * Buffers setup * \***************/ +static +struct sk_buff *ath5k_rx_skb_alloc(struct ath5k_softc *sc, dma_addr_t *skb_addr) +{ + struct sk_buff *skb; + unsigned int off; + + /* + * Allocate buffer with headroom_needed space for the + * fake physical layer header at the start. + */ + skb = dev_alloc_skb(sc->rxbufsize + sc->cachelsz - 1); + + if (!skb) { + ATH5K_ERR(sc, "can't alloc skbuff of size %u\n", + sc->rxbufsize + sc->cachelsz - 1); + return NULL; + } + /* + * Cache-line-align.
