From: Ivo van Doorn Date: Sun, 6 Jan 2008 22:41:28 +0000 (+0100) Subject: rt2x00: Determine MY_BSS from descriptor X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e56d38d5d0bda89228821902af297a46b5fdb80;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rt2x00: Determine MY_BSS from descriptor Use the MY_BSS descriptor field to determine if the received frame belongs to the same BSS as the interface. This can be used by rxdone to determine if the frame should be updated or not. Signed-off-by: Ivo van Doorn Signed-off-by: John W.
