Log message:
Rework iwm(4) Tx rate selection.
Ask firmware to retry at a constant Tx rate instead of successively lower
rates. This provides better feedback to Tx rate scaling algorithms in our
kernel and thus increases Tx throughput, especially on clean channels.
Make the driver fall back to CCK rates on 2 GHz channels if 11n MCS
don't work. Previously, we were relying on firmware to do this for us.
Tested on 7260, 7265, 8260, 8265 by me, jcs@, tb@, solene@, Matthias Schmidt.
