This change improves the maintainability of these drivers. No functionality is changed. Signed-off-by: Larry Finger Signed-off-by: John W. Linville

mac80211: provide sequence numbers

2008-10-31T23:00:12Z

I've come to think that not providing sequence numbers for the normal STA mode case was a mistake, at least two drivers now had to implement code they wouldn't otherwise need, and I believe at76_usb and adm8211 might be broken. This patch makes mac80211 assign a sequence number to all those frames that need one except beacons. That means that if a driver only implements modes that do not do beaconing it need not worry about the sequence number. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

rtl818x: merge tx/rx descriptor flags

2008-08-22T20:29:48Z

Tx/Rx descriptor flags are common between rtl818x devices, only with additions for newer chips, thus use same flags in the code. Signed-off-by: Herton Ronaldo Krzesinski Signed-off-by: John W. Linville

rtl8187: Fix lockups due to concurrent access to config routine

2008-08-01T19:31:35Z

Some users of the RTL8187B have experienced difficulties since commit 49292d56352a6ab90d04c3448dd8b6106dfef2d6 that introduced the power management wext hooks. This difficulty has not made much sense until it was realized that it was possible for mac80211 to make a call to the config routine while that routine was already being executed. On this device, it is necessary to loopback the TX when changing channels. Unless this is properly restored, the device will lockup. A mutex now protects the device state, and the private data in several places. The problem was found by Herton Ronaldo Krzesinski , who also suggested this type of fix.

rtl8187: Improve wireless statistics for RTL8187B

2008-07-29T20:55:08Z

Wireless statistics produced by the RTL8187B driver are not particularly informative about the strength of the received signal. From the data sheet provided by Realtek, I discovered that certain parts of the RX header should have the information necessary to calculate signal quality and strength. With testing, it became clear that most of these quantities were very jittery - only the AGC correlated with the signals expected from nearby AP's. As a result, the quality and strength are derived from the agc value. The scaling has been determined so that the numbers are close to those obtained by b43 under the same conditions. The results are qualitatively correct. Statistics derived for the RTL8187 have not been changed. The RX header variables have been renamed to match the quantites described in the Realtek data sheet.

rtl8187: Fix for TX sequence number problem

2008-07-29T20:55:08Z

"mac80211: fix TX sequence numbers" broke rtl8187. This patch makes the same kind of fix that was done for rt2x00. Note that this code will have to be reworked for proper sequence numbers on beacons. In addition, the sequence number has been placed in the hardware state, not the vif state. Signed-off-by: Larry Finger Signed-off-by: John W. Linville

mac80211: move TX info into skb->cb

2008-05-22T01:48:11Z

This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

cfg80211 API for channels/bitrates, mac80211 and driver conversion

2008-02-29T20:19:32Z

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. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: dont use interface indices in drivers

2008-01-28T23:09:36Z

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 Signed-off-by: John W.
