[PATCH] sky2: force early transmit status
Need to force a transmit coalesce timer restart after processing transmit packets. Otherwise, can get transmit status after last update and chip doesn't send the next one. Can go with the chip defaults for coalescing timers, except for Tx timer which needs to be bigger. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
