Some of the supported ethernet cards are 10/100 (fxp0 - Intel EtherExpress Pro/100, de0 - DEC DC21140, vx0 - 3Com 3c590). Shouldn't they autonegotiate to 100BaseT when connected to a 100BaseT network? I have tried to connect two FreeBSD 2.1.5 machines with Intel and DEC chip based cards with an ethernet X-wire - the 100 LED goes on but packets cannot be transmitted without errors. (seems like some PHY config problem in the driver...) Is it correct that fast ethernet hosts should only use the "standard" IEEE 802.2 encapsulation (RFC 1042) and not the classical Ethernet ecapsulation (RFC 894)? Is this beeing observed by other OS? As far as I can see, the Ethernet sublayer in FreeBSD only supports the RFC 894 style encapsulation for IP. If this is a problem are there any fixes? Bernhard
