[PATCH 1/4] b44: timer power saving

[Stephen Hemminger <shemminger@linux-foundation.org>]

[-- Attachment #1: b44-modtimer.patch --]
[-- Type: text/plain, Size: 1090 bytes --]

Make the PHY and statistic timer run on one second boundary
for powersaving.

On resume, the driver should check for link up immediately, to
get online faster (rather than waiting for the next second).
