The features enabled are of course card/driver specific. I'm afraid
there's no "catch-all" set I can think of.

For instance, the features required for wl12xx cards are:
HT_CAP_INFO_GREEN_FIELD, HT_CAP_INFO_SHORT_GI20MHZ, HT_CAP_INFO_RX_STBC_1

Should I initially mask only those in, and others can gradually add to the mask?
