Howdy,
Just noticed a line of code that struck me as odd and so I am writing just
in case it is a bug:
http://dpdk.org/browse/dpdk/tree/drivers/net/mlx5/mlx5_rxtx.c#n1014
Specifically the check "(mpw.length != length)" in mlx_tx_burst_mpw() looks
like a descriptor-format optimization for the special case where
consecutive packets on the wire are exactly the same size. This would
strike me as peculiar.
Just wanted to check, is that interpretation correct and if so then is this
intentional?
Cheers,
-Luke
