wil6210: add scatter-gather support When setting fragmented skb for Tx, assign skb to the last descriptor and set number of fragments in the 1-st one On Tx complete, HW sets "DU" bit in Tx descriptor only for the last descriptor; so search for it using number of fragments field. Middle descriptors may have "DU" bit not set by the hardware. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
