staging: vt6656: vnt_update_ifs vendor changes to uSIFS/uDIFS
The latest vendor code makes changes to uSIFS and uDIFS. The orginal codes have been rearranged into a fall through switch statement. These reduce the time that device allows to TX packets and improves throughput. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
