[PATCH 1/2] mac80211: Use G mandatory rates in 2GHz band

[Bruno Randolf <br1@einfach.org>]

This changes the mandatory (basic) rates in the 2GHz band to the ERP mandatory
rates (1, 2, 5.5, 11, 6, 12, 24Mbps - as defined in 802.11 section 19.1.)
instead of the "B" mode basic rate (1Mbps - why not 2Mbps too?).

B-only drivers (are there any?) should still work with this change, since they
simply don't have the faster rates. The functional change is that we now
default to faster basic rates, but as far as i can tell this is only really
used in IBSS code (STAs have to adapt to their AP).

BTW: Is there a way to configure mac80211 to B-only mode or G-only mode? When
this is the case this has to be revised...
