I am currently testing the new Netgear FA310TX NIC (DEC 21140-AF chipset) under 2.2.6-R. I've got it connected to a Netgear fast ethernet switch. The switch is set to auto-sense the duplexing mode (though setting it to full-duplex does not seem to change the problem I'm about to describe). Using this configuration, the driver seems to initialise the card correctly. The media is reported as "autoselect (100baseTX <full-duplex>)" by ifconfig. If I force a line break (by pulling out a connector), the driver reports: /kernel: de0: link down: cable problem? /kernel: de0: autosense failed: cable problem? ifconfig now reports the media type merely as "autoselect". If I plug the cable back in, ifconfig once again reports the media type as "autoselect (100baseTX <full-duplex>)" and the status as "active", BUT the NIC is not functioning. Only when I force an interface reset with "ifconfig de0 down" does the driver report: /kernel: de0: enabling Full Duplex 100baseTX port If I then bring it back up with "ifconfig de0 up", everything works again. So I tried things differently: I forced the media detection with "ifconfig de0 medial 100baseTX mediaopt full-duplex". ifconfig now reports the media correctly as "100baseTX <full-duplex> status: active". I force a line break and get the same error messages, but ifconfig now reports the interface status as "no carrier". If I plug the line back in, the status _stays_ at "no carrier". The only thing that seems to revive it then is setting the media back to "autoselect", and _then_ bouncing the interface down and back up. Is this behaviour standard? -- V Johann Visagie | Email: wjv@CityIP.co.za | Tel: +27 21 419-7878 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
