3.1.

Enabling network interface

Enable any Chelsio T6 network interface using the following command:
[root@host~]# ifconfig ccX <ip_address> up
For T5 and T4, use cxlX and cxgbeX respectively.
3.2.

Enabling TCP Offload

Enable TCP offload on a T6 interface using ifconfig. An error usually indicates that t4_tom is not
loaded.
[root@host~]# ifconfig ccX toe
For T5 and T4, use cxlX and cxgbeX respectively.
If successful, TOE4 and TOE6 will be displayed in the list of the enabled options as shown in
example below:
When a TOE capable interface is the outbound path to a destination to which a new connection
is being established, the connection should be offloaded automatically. Verify with netstat:
[root@host~]# netstat -np tcp | grep toe
