tg3: Use NET_IP_ALIGN
This patch replaces hardcoded 2's with the NET_IP_ALIGN constant or
TG3_RAW_IP_ALIGN where appropriate. Some platforms can redefine the
NET_IP_ALIGN definition to zero if unaligned DMA transfers cost more
than the IP header alignment gains. This patch represents a
performance improvement when using the 5701 on these platforms.
The copy path can be avoided.
TG3_RAW_IP_ALIGN is used in cases where we always want to align the
IP header on dword boundaries.
