atheros hardware has a problem with the rx timestamp of some IBSS beacons when they caused a TSF update (they have the same BSSID). the rx timestamp is wrong especially if the beacon frames get bigger than 78 byte (at least on AR5213 and AR5414 hardware). in that case ath5k_extend_tsf() will assume a rs_tstamp overflow and give us a timestamp too far in the past which will cause mac80211 to merge IBSS on every beacon (which is not necessary since the BSSID already matches). but in this case we know that the HW must have synced to the beacons TSF and the rx timestamp must be later than that so we can adjust mactime accordingly. also rename the function to ath5k_check_ibss_tsf() and change comments, since "hw merge" is better described as a TSF update. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

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: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

Cleanup after API changes patch (checkpatch.pl stuff) and on ath5k_hw_channel() make use of the existing ath5k_channel_ok() instead of re-implementing the checks again. This was necessary to make the code cleaner and fit the 80-chars wide limit so sending it within the same patch. Finally make a note that we *may* eventually move cap_range stuff to struct wiphy (band frequency range capabilities). This information can later be exported to userspace, for example, and giving it access to mac80211 and drivers in general can come in handy.

when setting up the tx descriptors for the hardware we must account for any padding between the header and the data we might have added previously. frame len is the length of the frame in the air (including FCS but no padding) and buffer len is the length of the buffer (including padding, but without FCS). changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's easier to add that in the function where we need it. before this fix we sent trailing zero bytes after the packet (because frame len included the padding) which was not a big problem without WEP, but with WEP this resultes in a wrong WEP checksum and the packet is discarded - which is how i noticed at all ;) an easy way to run into header padding problems, btw, is to connect to a QoS (WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer and will require padding. this patch applies on top of luis latest patch series from 04.02.2008. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC Signed-off-by: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

in "11.1.2.2 Beacon generation in an IBSS" the IEEE802.11 standard says, each STA should... "b) Calculate a random delay uniformly distributed in the range between zero and twice aCWmin × aSlotTime,". configure cwmin and cwmax of the beacon queue in IBSS mode according to this. unfortunately beacon backoff does not work reliably yet, so i suspect we have a problem somewhere else, since the same settings (and similar beacon timer configuration) work for madwifi. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

use SWBA (software beacon alert) interrupts to keep track of the next beacon time und check if a HW merge (automatic TSF update) has happened on every received beacon with the same BSSID. this is necessary because the atheros hardware will silently update the local TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon timers no beacons are sent until the timers wrap around (typically after about 1 minute). this solution is not very nice, since we have to look into every beacon, but there is apparently no other way to detect HW merges. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD Signed-off-by: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

update ath5k_beacon_update_timers() for better beacon timer calculation in a variety of situations. most important is the possibility to call it with the timestamp of a received beacon, when we detected that a HW merge has happened and we need to reconfigure the beacon timers based on that. we call this from the mac80211 callback reset_tsf now instead of beacon_update, and there will be more use of it in the next patch. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: NBruno Randolf <bruno@thinktube.com> Signed-off-by: NJohn W.

This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.
