    tg3: Use NET_IP_ALIGN · ad829268
    Matt Carlson authored
    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.
