Subject: [PATCH] ARCNET: fix hard_header_len limit

For arcnet the bare minimum header only contains the 4 bytes to
specify source, dest and offset (1, 1 and 2 bytes respectively).
The corresponding struct is struct arc_hardware.

The struct archdr contains additionally a union of possible soft
headers. When doing $insertusecasehere packets might well
include short (or even no?) soft headers.

For this reason only use arc_hardware instead of archdr to
determine the hard_header_len for an arcnet device.
