net: prefer ETHER_ADDR_LEN over ETH_ADDR_LEN

[jacob.e.keller_intel.com]

Summary

A couple of drivers and one place in if.c use ETH_ADDR_LEN, even though
net/ethernet.h provides an equivalent ETHER_ADDR_LEN definition.

Cleanup all of the locations which refer to ETH_ADDR_LEN to use the
standard ETHER_ADDR_LEN instead.

Adding @jpaetzel since he seemed to be the last person making updates to oce(4); is this change ok to make there? There's no functional change.

[jpaetzel]

For the OCE change that is fine.

Don't remove the extra whitespace in if.c
