wil6210: Add support for large packets
It is possible to configure driver using mtu_max module parameter by setting it to value in range of 68..7920 inclusive. This is sub-optimal performance-wise in case packet is larger than 1 page. mtu_max default value is 2228. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
