[PATCH] gianfar: Add support enhanced TSEC features on the MPC 8548
Jeff, Just incase this got lost in the recent netdev mailing list transition here is a nicer version of Andy's patch for gianfar. - kumar * TCP/IP/UDP checksumming and verification * VLAN tag insertion/extraction * Larger multicast hash-table * Padding to align IP headers Also added: * msg lvl support * Some whitespace cleanup Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Kumar Gala <kumar.gala@freescale.com>
