Software/Driver Loading

Please ensure that all inbox drivers are unloaded before proceeding with
Important
unified wire drivers:
[root@host~]# rmmod csiostor cxgb4i cxgbit iw_cxgb4 chcr cxgb4vf cxgb4
libcxgbi libcxgb
Before proceeding, please ensure that Unified Wire is installed with DCB support as mentioned
in previous section. The switch ports need to be enabled with DCBX configuration (Class
mapping, ETS and PFC).
Upon loading the network/storage driver and interface bringup, firmware completes DCBX
negotiation with the switch.
[root@host~]# modprobe cxgb4
[root@host~]# modprobe t4_tom
[root@host~]# ifconfig ethX up
[root@host~]# modprobe csiostor
The negotiated DCBX parameters can be reviewed at
/sys/kernel/debug/cxgb4/<PF4_id>/dcb_info
