flowid is specified by MS & Intel only for IPv4 traffic (hash
function, which is used to determine queue is defined only for IPv4
packet header). All other traffic (PPPoE, IPv6, etc.) goes into queue
0. There is nothing could be done on driver level, it is firmware (and
"standard") problem.
I was told, that top-level ("server-grade") 1G and 10G Intel NICs
have configurable user-defined filters (think: firewall and QoS in
hardware), and, may be, it could be done on this level, but I don't
know any open-source drivers, which support this feature.
