lshw -class network shows nics DISABLED
 
Notice the bottom 2 entries for lshw -class network show:

*-network:0 DISABLED

The logical name for one of the cards is eth1, and although lshw shows it as being disabled, it's passing traffic, the RX and TX continue to rise in ifconfig. What does this "*-network:0 DISABLED" mean?

Code:

[root@oracle_backup network-scripts]# lshw -class network

A node is marked as DISABLED if the node has been disabled by a configuration, some hardware failure, etc.
Use dmesg to dump message relative to disabled device to find out what's going on.
