Does the debian kernel sends the gratuitous arp ?

[Balaji G <gbalajieie@gmail.com>]

Hi,

    I am using "Debian GNU/Linux 11 (bullseye)" with kernel version 5.16.12.

When i do a link up/down i don't see any Gratuitous ARP being sent.

# echo 1 > /proc/sys/net/ipv4/conf/eno5np0/arp_notify
# ip link set down dev eno5np0
# ip link set up dev eno5np0

Captured all the packets via tcpdump & the tcpdump is not showing any Gratuitous ARP packets.

But, with the same commands i could see the Gratuitous ARP being sent in Red hat.9.0 (Plow). 

So, please let me know if this is a specific scenario in Debian 11 ??

Thanks,

Balaji
