2008-03-07ath5k: work around wrong beacon rx timestamp in IBSS modeBruno Randolf
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: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

* make struct ath5k_desc clearer by directly including unions of structures, which correspond to the hardware descriptors of different HW versions (5210 and 5212). before they were casted at onto ath5k_desc at different points (e.g. ds_hw[2]). * rename some structures and variable names to make their use clearer, e.g. struct ath5k_hw_4w_tx_desc to ath5k_hw_4w_tx_ctl. * substitute "old" with "5210" and "new" with "5212" (eg. rename ath5k_hw_proc_new_rx_status() to ath5k_hw_proc_5212_rx_status()) because old and new are relative and we might have a newer structure at some point. * unify structs ath5k_hw_old_rx_status and ath5k_hw_new_rx_status into one ath5k_hw_rx_status, because they only differ in the flags and masks. drivers/net/wireless/ath5k/ath5k.h: Changes-licensed-under: ISC drivers/net/wireless/ath5k/debug.c: Changes-licensed-under: GPL drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC drivers/net/wireless/ath5k/hw.h: Changes-licensed-under: ISC Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John 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.

2008-02-15ath5k: correct padding in tx descriptorsBruno Randolf
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: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: use SWBA to detect IBSS HW mergesBruno Randolf
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: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: better beacon timer calculationBruno Randolf
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: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: beacon interval is in TUBruno Randolf
the beacon interval is passed by mac80211 in TU already, so we can directly use it without conversion. also update the comments about TU (1 TU is defined by 802.11 as 1024usec). 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/base.h: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: use 3 instead of 0x00000003Bruno Randolf
reviewed beacon timer initialization with register traces from madwifi: what we are doing is correct :). one minor fix: use 3 instead of 0x00000003 - it's more readable. drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: Fix frame duration oopsLuis R. Rodriguez
This patch fixes an oops which was introduced as a regression by commit fd640775bd16e1df50c867cc547af0, on the patch titled, "mac80211: dont use interface indices in drivers". ieee80211_generic_frame_duration() now relies on sdata->flags which itself gets set upon bringing the interface up. We check for the virtual interface now before setting the rate duration registers. After the mode changes are introduced onto mac80211 we should revisit these changes. This patch was tested on the following cards: 1) BG card: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) RF2112A 2GHz radio found (0x46) 2) ABG card: Atheros AR5213A chip found (MAC: 0x59,PHY: 0x43) RF5112A multiband radio found (0x36) Signed-off-by: Luis R.

2008-01-28mac80211: dont use interface indices in driversJohannes Berg
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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
