Arrrrgh...
As usual, just after I fire off an email I find the answer...
mii-tool does indeed provide the link status information on RH 6.2. It
appears that it just wasn't happy being compiled on 6.2, or at least on
my system. I grabbed:
ftp://ftp.valinux.com/pub/support/flory/mii-tool-static and
ftp://ftp.valinux.com/pub/support/flory/mii-diag-static
and all is happy now:
[root@stud mtibor]# mii-tool eth0
eth0: no autonegotiation, 10baseT-HD, link ok
[root@stud root]# mii-diag eth0
Basic registers of MII PHY #24: 3100 786d 2000 5c01 01e1 0021 0000 0000.
Basic mode control register 0x3100: Auto-negotiation enabled.
You have link beat, and everything is working OK.
Your link partner is generating 10baseT link beat (no autonegotiation).
