Hi all,

anyone got 3Com 3c905B-COMBO network card (Fast EtherLink XL PCI)
working with 10base2/BNC?

I just bought one and I can't figure it out. It has BNC connector and
should be supported according to man xl page.

With ifconfig_xl0="DHCP" in /etc/rc.conf and BNC cable connected (with
terminator) ifconfig reports:

xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=9<RXCSUM,VLAN_MTU>
        inet6 fe80::204:76ff:feed:6697%xl0 prefixlen 64 scopeid 0x1
        ether 00:04:76:ed:66:97
        media: Ethernet autoselect (none)
        status: no carrier

dhclient reports "xl0: no link..... giving up"


Now, if I manually try to switch to BNC media with:

# ifconfig xl0 media 10base2/BNC

I get:

# xl0: selecting AUI media, half-duplex

and a kernel panic (trap 12).

The BNC cable itself works with another box. More information below.
Any help appreciated.
