* iwlwifi: move rate registration to module loadReinette Chatre2008-04-011-3/+3
| | | | | | | | | | | | Having rate registration during module load enables the use of error checking as well as reliable registration/unregistration pairing. Previously this was not possible as rate registration was done during _probe where _probe could be run for more than one device on the system.

* mac80211: A-MPDU MLME use dynamic allocationRon Rindjunsky2008-03-271-1/+1
| | | | | | | | | | | This patch alters the A-MPDU MLME in sta_info to use dynamic allocation, thus drastically improving memory usage - from a constant ~2 Kbyte in the previous (static) allocation to a lower limit of ~200 Byte and an upper limit of ~2 Kbyte.

* mac80211: RCU-ify STA info structure accessJohannes Berg2008-03-061-12/+15
| | | | | | | | | | | | | | | This makes access to the STA hash table/list use RCU to protect against freeing of items. However, it's not a true RCU, the copy step is missing: whenever somebody changes a STA item it is simply updated. This is an existing race condition that is now somewhat understandable. This patch also fixes the race key freeing vs. STA destruction by making sure that sta_info_destroy() is always called under RTNL and frees the key.

* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-39/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

* iwlwifi: A-MPDU Tx activation by load measuresRon Rindjunsky2008-02-291-18/+186

* iwl4965: fix cannot find a suitable rate issueMohamed Abbas2008-01-281-5/+8
| | | | | | | | | | | | | | | | This patch fixes the iwl4965 problem for "Can not find a suitable rate issues." by making rs_switch_to_mimo and rs_switch_to_siso functions return -1 when CONFIG_IWL4965_HT is not selected. They used to return 0, which means we can switch to HT rate causing the rate scale problem and the error message.
