By default stats counted by HW are returned via the original ndo_get_stats64()
api. Stats counted in SW are returned via ndo_get_offload_stats() api.
Small script to demonstrate vfpr stats in switchdev mode.

device by storing the netdev pointer along
with port id so that if TC decides to redirect or mirror the new netdev will not
try to interpret it.
This is mostly for SR-IOV devices since switches don't have lower netdevs today.
