62c678bc4fSBill Paul.Pp 6387f3d8beSChristian BruefferThe LXT1001 supports fiber PHYs and also a GMII port for use with 6487f3d8beSChristian Brueffer10/100/1000 copper PHYs, however there are currently no NICs on the 6587f3d8beSChristian Brueffermarket that use this feature. 6687f3d8beSChristian Brueffer.Pp 67c678bc4fSBill PaulThe LXT1001 supports TCP/IP checksum offload for receive and 68c678bc4fSBill PaulVLAN-based filtering as well as a 64-bit multicast hash filter. 69c678bc4fSBill PaulIt also supports jumbo frames, which can be configured 70c678bc4fSBill Paulvia the interface MTU
