ip link shows this:

[root@0-25-90-68-79-4a log]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000
    link/ether 00:25:90:68:79:4a brd ff:ff:ff:ff:ff:ff
5: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether 00:25:90:68:79:4a brd ff:ff:ff:ff:ff:ff
8: gre0: <NOARP> mtu 1476 qdisc noop state DOWN

    link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff
13: br35978f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff

Here, the interface 35978f0 is the virtual interface which is tied to the bridge br 35978f0. I've already done ifconfig 35978f0 down and brctl delif br35978f0 35978f0.

But how do I delete interface 35978f0?

You can use sudo ip link delete to remove the interface.
