"to = (currticks() + RTL_TIMEOUT)" has possibilities to wrap around. If it
does, the condition "(currticks() < to)" becomes invalid and immediately
leads to tx timeout error. This patch introduces the fine-graded udely(10)
loops to ease the impact of wrapping around.

Change return values of init() functions in all Ethernet drivers to conform
to the following:
>=0: Success
<0: Failure
All drivers going forward should return 0 on success. Current drivers that
return 1 on success were left as-is to minimize changes.
