netstat -i shows tx-errors

[Howard, Chris]

I have a Dell 2850 running Red Hat EL 4.x
 
One of the network interfaces, I believe it is a dual port e1000 card,
is showing this:
 
eth0      Link encap:Ethernet  HWaddr 00:14:22:24:2F:D4  
          inet addr:10.202.1.4  Bcast:10.202.1.255  Mask:255.255.255.0
          inet6 addr: fe80::214:22ff:fe24:2fd4/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:158347 errors:0 dropped:0 overruns:0 frame:0

          Base address:0xecc0 Memory:fe6e0000-fe700000 

 
What might be the problem with TX-errors and TX-carrier?  I have not been
able to find any information about TX-carrier and what that means.
 
It is set up for autonegotiate, and the switch it is attached to, I believe the switch
is bumping it down to 100/half-duplex.  Would that cause the errors?
