Hi,

PPPoE will not be hashed according to RSS on the 1g/10g (igb, ixgbe)
intel hardware. you're going to have to figure out some other method
for traffic redistribution.

If it's inside GRE, then it's IPv4/IPv6 and thus yes, you can do
symmetric hashing. But if it's raw pppoe coming in, you're SoL.
