Subject: tc mqprio offload command error

Hello Folks,

I am trying to set below command to try mqprio offload on 4.18 kernel. It is throwing the flowing error.

# tc qdisc add dev eth0 root mqprio num_tc 2 map 1 1 1 1 0 0 0 0

I can't really make out what's wrong with the above command, since this works fine with other OS kernels.
Any thoughts if it is something broken on upstream kernel ?

Thanks,
Manish
