When using udev >=177 libertas driver does not load properly the firmware [1]. The patches 0001-0016 were taken from [2] and can be viewed at [3]. Patch 0017 I created to fix compiler complaining for missing symbol is_interrupt when DEBUG set. The patch series was tested with meta-gumstix on overo with udev-175 and udev-182.

Subject: [PATCH 05/17] libertas: remove dump_survey implementation
|
|
|
|
libertas provides a dump_survey implementation based on reading of
|
|
a RSSI value. However, this RSSI value is calculated based on the
|
|
last received beacon from the associated AP - it is not a good
|
|
way of surveying a channel in general, and even causes an error
|
|
if the card is not associated to a network.
|
|
|
|
As this is not appropriate as a survey, remove it. This fixes an
|
|
issue where something in userspace is repeatedly calling site-survey
|
|
during boot, resulting in many repeated errors as the RSSI value cannot
|
|
be read before associating.
