I've uploaded to codereview a proposed change to address this bug. It is here:

http://codereview.appspot.com/855042

This change causes some tests to fail - specifically, the
wireless/wifi-simple-adhoc-grid example, and the routing-olsr-regression
testsuite.

In this case it is actually the tests that are at fault (or, at least, need
updating). In the wifi-simple-adhoc-grid test and the bug780-test part of the
routing-olsr-regression testsuite, 802.11b rates were being requested with the
Wi-Fi PHY standard left at the default of 802.11a. The fix here is to set the
standard to 802.11b in the test.

In the tx-regression-test part of routing-olsr-regression, the problem was that
the reference traces needed to be updated given the control response rate fix.
In this case I have also modified the test to set the standard to 802.11a for
clarity.

I have addressed these test issues in a separate changelist which is available
for your perusal here:
