* Crypto api changes:Sam Leffler2008-09-211-2/+2
| | | | | | | | | | | | | | | | | o don't use the key index to identify when the driver has been asked to allocate a key slot, use an explicit flag; allows drivers to force s/w fallback for entries in the global table o change callback api to allocate driver resources for a crypto key: - de-const the key parameter so drivers can muck with the flags - on callback failure don't automatically try to setup s/w crypto; instead the driver must now mark the key entry for s/w crypto and the caller will re-attach the cipher module NB: api change permits drivers more control over fallback to s/w crypto (e.g. based on a limited number of h/w key slots) Notes: svn path=/head/; revision=183248

* Change the calling convention for ic_node_alloc to deal withSam Leffler2008-06-071-3/+4
| | | | | | | | | | | | | | | some longstanding issues: o pass the vap since it's now the "coin of the realm" and required to do things like set initial tx parameters in private node state for use prior to association o pass the mac address as cards that maintain outboard station tables require this to create an entry (e.g. in ibss mode) o remove the node table reference, we only have one node table and it's unlikely this will change so this is not needed to find the com structure Notes: svn path=/head/; revision=179643

* Cleanup power handling and fix suspend/resume:Sam Leffler2008-05-291-24/+61
| | | | | | | | | | | | | | | | | | | | | | o do not put the chip into full sleep in ath_stop as it gains nothing and causes many parts to hang in ath_detach because we may touch the chip during vap teardown; this may also fix issues with unloading the module o add a note in ath_detach to explain ath_hal_detach puts the chip in low power mode; this is useful to know as it means unloading the module will place a pci device in the lowest possible power state o leave an #ifdef notyet marker for powering down the chip when a device is marked down; we can't do that until we handle all the ways the driver may be entered and touch the chip o fix resume by reloading the h/w key cache as it's been clobbered (for pci) by the socket being powered off; for station mode we directly stop+init the chip and then simulate a beacon miss to get the upper layers sync'd up; for other configs we must brute force stop+start the vaps so they go through the state machine Notes: svn path=/head/; revision=179401

| | | | | | | | | | | | | | | | o add IEEE80211_C_STA capability to indicate sta mode is supported (was previously assumed) and mark drivers as capable o add ieee80211_opcap array to map an opmode to the equivalent capability bit o move IEEE80211_C_OPMODE definition to where capabilities are defined so it's clear it should be kept in sync (on future additions) o check device capabilities in clone create before trying to create a vap; this makes driver checks unneeded o make error codes return on failed clone request unique o temporarily add console printfs on clone request failures to aid in debugging; these will move under DIAGNOSTIC or similar before release Notes: svn path=/head/; revision=178957

* Unify all the wifi *_ioctl routinesAndrew Thompson2008-05-011-13/+7
| | | | | | | | | | | | | | | | | - Limit grabbing the lock to SIOCSIFFLAGS. - Move ieee80211_start_all() to SIOCSIFFLAGS. - Remove SIOCSIFMEDIA as it is not useful. - Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no affect as there is no input/output path in the vap parent. The vap code will handle the reinit of the mac address changes. - Split off ndis_ioctl_80211 as it was getting too different to wired devices. This fixes a copyout while locked and a lock recursion.

| | | | | | | | | | | | | | | | | | | | | | o add driver callback to handle notification of beacon changes; this is required for devices that manage beacon frames themselves (devices must override the default handler which does nothing) o move beacon update-related flags from ieee80211com to the beacon offsets storage (or handle however a driver wants) o expand beacon offsets structure with members needed for 11h/dfs and appie's o change calling convention for ieee80211_beacon_alloc and ieee80211_beacon_update o add overlapping bss support for 11g; requires driver to pass beacon frames from overlapping bss up to net80211 which is not presently done by any driver o move HT beacon contents update to a routine in the HT code area Reviewed by: avatar, thompsa, sephe Approved by: re (blanket wireless) Notes: svn path=/head/; revision=172211
