+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fivd%2Frt2x00.git;a=commitdiff_plain;h=1ddf4bdad5f51a799ee580e125dda19dd18daa39
+
+rt2x00: Implement support for 802.11n
+
+Extend rt2x00lib capabilities to support 802.11n,
+it still lacks aggregation support, but that can
+be added in the future.
