Как мне удалить задержку пересылки моего моста с помощью ip / iproute2?

Я знаю, что это возможно с помощью brctl setfd , но мне было предложено не использовать brctl и вместо этого использовать iproute2 или ip (поскольку brctl устарел: https://lwn.net/Articles/435845/ ). Если этот совет верен, как мне установить нулевую задержку пересылки моего моста с помощью ip / iproute2?

Использование iproute2:

# ip link add br0 type bridge   # forward_delay 0 can also be specified here
# ip link set br0 type bridge forward_delay 0
# ip -d link sh br0
