Subject: [PATCH 1/3] ieee80211: Replace bit shifts with the BIT() macro for WLAN_CAPABILITY_*.
It is neater and more consistent with the rest of the document to use the
BIT() macro from 'linux/bitops.h' to define the WLAN_CAPABILITY_*
bitmasks. In the case of WLAN_CAPABILITY_DMG_TYPE_{IBSS, PBSS, AP},
bitshifting integers by 0 does nothing, so there is no reason to do it in
the code; replace these values with plain integers.
