Bridge Ageing Time Configuration

[bidel65]

Expected Behavior

change and affect default value (300) of aging time.

Actual Behavior

Changing the aging time has no effect on TBD system. It stuck at its default value 300 seconds.

Steps to Reproduce the Problem

Platform:
TBD, Linux 5.15.90-yocto-standard-onl armv7l GNU/Linux
Procedure:
$ ip -p -d -j link show vbr0 | grep "ageing_time" "ageing_time": 30000,
$ sudo ip link set dev vbr0 type bridge ageing_time 2000
$ ip -p -d -j link show vbr0 | grep "ageing_time"
"ageing_time": 2000,
$ sudo bridge fdb del 00:0b:ab:63:ef:89 dev eth1 master vlan 1
$ sudo bridge -s fdb show br vbr0 dev eth1 state dynamic
$
$ ping 192.168.1.2 -c 2

Expected Results:
After 20 seconds The entry is cleaned up
Actual Results:
After 300 seconds The entry is cleaned up
And in result of command ‘brctl showstp swbridge’ , show new value of agin time that we set, but not
functionality.
