* Hoist 802.11 encapsulation up into net80211:Sam Leffler2009-03-301-381/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | o call ieee80211_encap in ieee80211_start so frames passed down to drivers are already encapsulated o remove ieee80211_encap calls in drivers o fixup wi so it recreates the 802.3 head it requires from the 802.11 header contents o move fast-frame aggregation from ath to net80211 (conditional on IEEE80211_SUPPORT_SUPERG): - aggregation is now done in ieee80211_start; it is enabled when the packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames are held on a staging queue according to ieee80211_ffagemax (net.wlan.ffagemax) to wait for a frame to combine with - drivers must call back to age/flush the staging queue (ath does this on tx done, at swba, and on rx according to the state of the tx queues and/or the contents of the staging queue) - remove fast-frame-related data structures from ath - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle per-node fast-frames state (we reuse 11n tx ampdu state) o change ieee80211_encap calling convention to include an explicit vap so frames coming through a WDS vap are recognized w/o setting M_WDS With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

* New periodic calibration scheme needed for 11n parts that haveSam Leffler2008-12-071-51/+78
| | | | | | | | | | | | | | | | | | multiple algorithms and potentially collect multiple samples. Instead of a single calibration interval we now have short and long intervals; the long interval roughly corresponds to the previous single interval. The short interval is used to speedup collection of samples and happens much quicker. We make calls using the short interval until we're told the calibration work is complete at which point we fallback to the long interval. In addition there is a much longer reset interval used to flush all calibration state and cause everthing to start anew. With these changes you can also disable calibration entirely by setting the long interval to zero. Notes: svn path=/head/; revision=185744
* Switch to ath hal source code. Note this removes the ath_halSam Leffler2008-12-011-2/+1
| | | | | | | | | | | | | | | | | | | | module; the ath module now brings in the hal support. Kernel config files are almost backwards compatible; supplying device ath_hal gives you the same chip support that the binary hal did but you must also include options AH_SUPPORT_AR5416 to enable the extended format descriptors used by 11n parts. It is now possible to control the chip support included in a build by specifying exactly which chips are to be supported in the config file; consult ath_hal(4) for information.

* Fix checks for fast frames negotiation. ni_ath_flags holds theSam Leffler2008-10-301-1/+1
| | | | | | | | | | | | | | | | | capabilities reported by the ap. These need to be cross-checked against the local configuration in the vap. Previously we were only checking the ap capabilities which meant that if an ap reported it was ff-capable but we were not setup to use them we'd try to do ff aggregation and drop the frame. There are a number of problems to be fixed here but applying this fix immediately as the problem causes all traffic to stop (and has not workaround).
