rtl8187: Fix lockups due to concurrent access to config routine

2008-08-20T18:05:10+00:00

With the rtl8187 driver, the config routine is not protected against
access before a previous call has completed. When this happens, the
TX loopback that is needed to change channels may cause the chip to
be locked with a reset needed to restore communications. This patch
entered mainline as commit 7dcdd073bf78bb6958bbc12a1a47754a0f3c4721.

The problem was found by Herton Ronaldo Krzesinski ,
who also suggested this type of fix.

rtl8187: Add missing priv->vif assignments

2008-04-15T18:51:57+00:00

This adds missing priv->vif assignments after "mac80211: don't use
interface indices in drivers" change. As rtl8180, rtl8187 also needs
priv->vif to be set, as without this an oops can happen in rtl8187_tx
function (priv->vif is passed to ieee80211_rts_duration).

cfg80211 API for channels/bitrates, mac80211 and driver conversion

2008-02-29T20:19:32+00:00

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.

mac80211: dont use interface indices in drivers

2008-01-28T23:09:36+00:00

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

Add rtl8180 wireless driver

2008-01-28T23:09:35+00:00

This patch adds a mac80211 based wireless driver for the rtl8180 and
rtl8185 PCI wireless cards.  Also included are some rtl8187 changes
required due to the relationship between that driver and this one.

Michael Wu is primarily responsible for the initial driver and rtl8185
support.  Andreas Merello provided the additional rtl8180 support.

Thanks to Jukka Ruohonen for the donating a rtl8185 card! It was very
helpful for the rtl8225z2 code.
