LXT1001 supports fiber PHYs and also a GMII port for use with 6287f3d8beSChristian Brueffer10/100/1000 copper PHYs, however there are currently no NICs on the 6387f3d8beSChristian Brueffermarket that use this feature. 6487f3d8beSChristian Brueffer.Pp 65c678bc4fSBill PaulThe LXT1001 supports TCP/IP checksum offload for receive and 66c678bc4fSBill PaulVLAN-based filtering as well as a 64-bit
