netmap ixgbevf mtu

[Joe Buehler]

I am having difficulties with netmap over top of ixgbevf when attempting to use a large MTU (say 9000 bytes).

Does the ixgbevf driver use 2048 byte buffers for RX regardless of the MTU or netmap buffer size?

I can send large frames just fine but inbound frames are passed via netmap as 2048 bytes max.  It is possible that netmap is passing frames in multiple pieces I suppose, I haven't checked that yet -- my code is looking at the frame headers only at the moment so would toss trailing pieces.
