Add Texas Instruments TNET100 'ThunderLAN' PCI NIC driver to the tree.
This driver supports the following cards/integrated ethernet controllers: Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100, Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port, Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated, Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX. It should also support Texas Instruments NICs that use the ThunderLAN chip, though I don't have any to test. If you've got a card that uses the ThunderLAN chip but isn't listed in the PCI vendor/product list in if_tl.c, try adding it and see what happens. The driver supports any MII compliant PHY at 10 or 100Mbps speeds in full or half duplex. (Those I've personally tested are the National Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation, hardware multicast filtering, BPF and ifmedia support are included. This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN ethernet and FreeBSD make for a nice combination.
