Hi Nikolay
The man page says that the bridge forward_delay is in units of
seconds, and should be between 2 and 30.
I've tested on a couple of different kernel versions, and this appears
to be not working correctly:
ip link set br0 type bridge forward_delay 2

ip link set br0 type bridge forward_delay 199
RTNETLINK answers: Numerical result out of range
ip link set br0 type bridge forward_delay 200
#
ip link set br0 type bridge forward_delay 3000
#
ip link set br0 type bridge forward_delay 3001

I've not checked what delay is actually being used here, but clearly
something is mixed up.
grep HZ .config
CONFIG_HZ_PERIODIC=y
# CONFIG_NO_HZ_IDLE is not set
# CONFIG_NO_HZ_FULL is not set
# CONFIG_NO_HZ is not set
CONFIG_HZ_FIXED=0
CONFIG_HZ_100=y
# CONFIG_HZ_200 is not set
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
# CONFIG_HZ_500 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=100
Thanks
Andrew
