Folks,
I am installing openstack and as you know i have lots of bridges and
vlan interface on my Linux CentOS 7.5
I was getting following error stack on 3.10 kernel and found this is
kernel bug which required kernel upgrade so now i have upgraded my
kernel to 4.17.12 but i am still seeing same kernel stack error on my
dmesg
I have disable TSO, LRO, SG & GSO on my NIC but still getting error
just wanted to understand what is this and why it popping up
