[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
