K 10 svn:author V 6 adrian K 8 svn:date V 27 2012-07-31T23:54:15.822003Z K 7 svn:log V 395 Allow 802.11n hardware to support multi-rate retry when RTS/CTS is enabled. The legacy (pre-802.11n) hardware doesn't support this - although the AR5212 era hardware supports MRR, it doesn't have all the bits needed to support MRR + RTS/CTS. The AR5416 and later support a packet duration and RTS/CTS flags per rate scenario, so we should support it. Tested: * AR9280, STA PR: kern/170302 END
