I felt kind of stupid at first for not noticing that, but then I noticed
that I don't have it:
(84) smkelly@edgemaster:~$ ifconfig -a
xl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 147.134.112.68 netmask 0xffffff00 broadcast 147.134.112.255
inet6 fe80::210:5aff:fec6:b4e4%xl0 prefixlen 64 scopeid 0x1
ether 00:10:5a:c6:b4:e4
media: Ethernet 10baseT/UTP (10baseT/UTP <half-duplex>)
(85) smkelly@edgemaster:~$ grep xl0 /var/run/dmesg.boot
xl0: <3Com 3c900B-TPO Etherlink XL> port 0xd800-0xd87f mem 0xd7000000-0xd70=
0007f irq 11 at device 9.0 on pci0
xl0: Ethernet address: 00:10:5a:c6:b4:e4
xl0: selecting 10baseT transceiver, half duplex
Which is strange, because I could swear Windows was able to detect it when
this NIC was in the Windows machine.
However, my desktop machine at work:
(1) smkelly@rooster:~$ ifconfig -a
xl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 147.134.2.73 netmask 0xfffffc00 broadcast 147.134.3.255
inet6 fe80::204:76ff:fe3a:8b00%xl0 prefixlen 64 scopeid 0x1
ether 00:04:76:3a:8b:00
media: Ethernet autoselect (10baseT/UTP)
status: active
xl0: <3Com 3c905C-TX Fast Etherlink XL> port 0xdc00-0xdc7f mem 0xff9ffc00-0=
xff9ffc7f irq 9 at device 11.0 on pci2
xl0: Ethernet address: 00:04:76:3a:8b:00
miibus0: <MII bus> on xl0
Is it miibus making the difference? I looked at if_xl.c, and I only see
ifm_status being set if icfg =3D=3D XL_XCVR_100BTX, XL_XCVR_AUTO, or
XL_XCVR_MII. Unfortunately my kernel skills are still lacking and I'm not
able to derive much from this except that I"m screwed and need to secretly
switch NICs when nobody is looking.
