mac80211: Add new callback set_coverage_class
Mac80211 callback to driver set_coverage_class() sets slot time and ACK timeout for given IEEE 802.11 coverage class. The callback is optional, but it's essential for long distance links. Signed-off-by: Lukas Turek <8an@praha12.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
