[PATCH] zd1211rw: Use softmac ERP handling functionality
This adds zd1211rw driver support for the softmac functionality I
added a while back. We now obey changes in basic rates, use short
preamble if it is available (but long if the AP says it's not),
and send self-CTS in the proper situations.
Locking fixed and improved by Ulrich Kunitz.
