This makes me curious because i believe people have used netmap with
the 82598 and achieved close to line rate even with 64-byte frames/one port,
and i thought (maybe I am wrong ?) the various 2-port NICs use 4 lanes per port.
So the number i remember does not match with your quote of 2.5Gt/s.
Are all 82598 using 2.5GT/s (which is a gen.1 speed) instead of 5 ?

Quoting 82598EB datasheet:
The PCIe v2.0 (2.5 GT/s) interface is used by the 82598EB as a host interface.
It supports x8, x4,
x2 and x1 configurations at a speed of 2.5 GHz. The maximum aggregated raw ban..
Actually I discovered this exactly with netmap and 82598*-DA2 NIC :)
Discussing the 82598 is moot because it has been replaced with the 82599
which supports x1-x8 at 5 GT/s. AFAIK you can't event buy the 82598 anymore.
