net/memif: add a Tx fast path
For memif non-zero-copy mode, there is a branch to compare
the mbuf and memif buffer size during memory copying. If all
mbufs come from the same mempool, and memif buf size >= mbuf
size, add a fast Tx memory copy path without the comparing
branch and with mbuf bulk free, otherwise still run the
original Tx path.
The removal of the branch and bulk free lead to considerable
performance uplift.
Test with 1p1q on Ampere Altra AArch64 server,
--------------------------------------------
buf size | memif >= mbuf | memif < mbuf |
--------------------------------------------
non-zc gain | 10.82% | 0.04% |
--------------------------------------------
zc gain | 8.86% | 3.18% |
--------------------------------------------
Test with 1p1q on Cascade Lake Xeon X86server,
--------------------------------------------
buf size | memif >= mbuf | memif < mbuf |
--------------------------------------------
non-zc gain | 7.32% | -0.85% |
--------------------------------------------
zc gain | 12.75% | -0.16% |
