[PATCH] Speedup link loss detection for 3c59x

[Martin Buck <mb-tmp-yvahk-argqri@gromit.dyndns.org>]

From: Martin Buck <mb-tmp-yvahk-argqri@gromit.dyndns.org>

Change the timer used for link status checking to check link every 5s,
regardless of the current link state. This way, link loss is detected as
fast as new link, whereas this took up to 60s previously (which is pretty
inconvenient when trying to react on link loss using e.g. ifplugd). This
also matches behaviour of most other Ethernet drivers which typically have
link check intervals in the low second range.
