help:: configuring two network interfaces--message->>ifconfig: ioctl (SIOCAIFADDR): File exists

[kamal kc]

i have run into a mysterious problem.
The thing is that i wanted to configure to NIC cards.
I just put the card in the slot and booted FreeBSD. The 
card was detected. When i wanted to configure the nic card using the 
ifconfig command the following error message was reported.
ifconfig: ioctl (SIOCAIFADDR): File exists
The same message was reported when i configured the rc.conf file and 
rebooted the computer.
Below i have copied the output of ifconfig and the rc.conf file
in case it could help solve the problem.
