[PATCH] if_sis conversion from if_watchdog to sis_watchdog

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

i made a patch which converts if_sis from using the deprecated
if_watchdog interface to using sis_watchdog. As an example i used the
if_rl and if_fxp conversion.

This patch is running on my internet router for > 12 hours and i seems
to work fine.

Cheers
Florian
