generation on or off as requested through ethtool.  However, this can
result in regenerating checksums in raw packets that should not be

on or off.  They are presented to the net core as one queue since it
does not know how to select between them.

with checksum generation off.

b43: Rewrite TX power adjustment

This patch rewrites the TX power recalculation algorithms to scale better
with changed enviromnent. If there's low
TX traffic, the power will be checked against the desired values
every 60 seconds.
If there is high TX traffic, the check is redone every 2 seconds. This improves
the reaction times a lot and confuses the rate control less.
It will also reduce the time it initially takes to tune to a new TX power
value. With the old algorithm it could take about 30 to 45 seconds to settle to
a new power value. This will happen in about two to four seconds now.

Some hardware configuration registers such as antenna and channel configuration
can only be written when the radio is enabled. Previously, we didn't consider
this, so some configuration items could be set inconsistently after reenabling

hardware when the radio is enabled. Configuration changes that are made while
the radio is off are postponed until the radio is switched back on. We also
leave the radio turned off during initialization and only enable it when
requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag,
because the device is now guaranteed to be completely initialized when brought
up by mac80211.
