mac80211: detect driver tx bugs

2008-07-24T16:14:02+00:00

When a driver rejects a frame in it's ->tx() callback, it must also
stop queues, otherwise mac80211 can go into a loop here. Detect this
situation and abort the loop after five retries, warning about the
driver bug.

This patch was added to mainline as
commit ef3a62d272f033989e83eb1f26505f93f93e3e69.

Thanks to Larry Finger  for doing the -stable
port.

mac80211: remove message on receiving unexpected unencrypted frames

2008-04-15T19:04:36+00:00

Some people are getting this message a lot, and we have traced it to
broken access points that much too often send completely empty frames
(all bytes zeroed, which they shouldn't do at all.)

Since we cannot do anything about such frames in any case except the
special case where we're debugging an AP, just remove the message.

mac80211: use short_preamble mode from capability if ERP IE not present

2008-04-09T14:33:49+00:00

When associating to a b-only AP where there is no ERP IE, short preamble
mode is left at previous state (probably also protection mode). In this
case, disable protection and use short preamble mode as specified in
capability field. The same is done if capability field is changed on-the-fly.

mac80211: correct use_short_preamble handling

2008-04-01T19:44:08+00:00

ERP IE bit for preamble mode is 0 for short and 1 for long, not the other
way around. This fixes the value reported to the driver via
bss_conf->use_short_preamble field.

mac80211: trigger ieee80211_sta_work after opening interface

2008-04-01T19:44:07+00:00

ieee80211_sta_work is disabled while network interface
is down. Therefore, if you configure wireless parameters
before bringing the interface up, these configurations are
not yet effective and association fails.

A workaround from userspace is calling a command like
'iwconfig wlan0 ap any' after the interface is brought up.

To fix this behaviour, trigger execution of ieee80211_sta_work from
ieee80211_open when in STA or IBSS mode.

rc80211-pid: fix rate adjustment

2008-03-04T23:36:35+00:00

Merge rate_control_pid_shift_adjust() to rate_control_pid_adjust_rate()
in order to make the learning algorithm aware of constraints on rates. Also
add some comments and rename variables.

This fixes a bug which prevented 802.11b/g non-AP STAs from working with
802.11b only AP STAs.

This patch was originally destined for 2.6.26, and is being backported
to fix a user reported problem in post-2.6.24 kernels.

mac80211: Fix initial hardware configuration

2008-02-15T18:44:19+00:00

On the initial device-open we need to defer the hardware reconfiguration
after we incremented the open_count, because the hw_config checks this flag
and won't call the lowlevel driver in case it is zero.

mac80211: Is not EXPERIMENTAL anymore

Remove the EXPERIMENTAL dependency, as the existing mac80211
features are stable.
