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. Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
