net: reset mac header in dev_start_xmit()
On 64 bit arches :
There is a off-by-one error in qdisc_pkt_len_init() because
mac_header is not set in xmit path.
skb_mac_header() returns an out of bound value that was
harmless because hdr_len is an 'unsigned int'
On 32bit arches, the error is abysmal.
This patch is also a prereq for "macvlan: add multicast filter"
