command:
#
esxcli network vswitch standard uplink add -u <uplink
device> -v <roce vswitch>
For example:
#
esxcli network vswitch standard uplink add -u vmnic0 -v
roce_vs

To create a vmknic interface on this port group and configure the IP, issue
the following command:
#
esxcfg-vmknic -a -i <IP address> -n <subnet mask> <roce port
group name>
For example:
#
esxcfg-vmknic -a -i 192.168.10.20 -n 255.255.255.0 roce_pg
