[dpdk-dev] [PATCH v1 00/48] net/mlx4: trim and refactor entire PMD

[Adrien Mazarguil]

The main purpose of this large series is to relieve the mlx4 PMD from its
dependency on Mellanox OFED to instead rely on the standard rdma-core
package provided by Linux distributions.

While compatibility with Mellanox OFED is preserved, all nonstandard
functionality has to be stripped from the PMD in order to re-implement it
through an approach compatible with rdma-core.

Due to the amount of changes necessary to achieve this goal, this rework
starts off by removing extraneous code to simplify the PMD as much as
possible before either replacing or dismantling functionality that relies on
nonstandard Verbs.

What remains after applying this series is single-segment Tx/Rx support,
without offloads nor RSS, on the default MAC address (which cannot be
configured). Support for multiple queues and the flow API (minus the RSS
action) are also preserved.

Missing functionality that needs substantial work will be restored later by
subsequent series.

Also because the mlx4 PMD is mostly contained in a single very large source
file of 6400+ lines (mlx4.c) which has become extremely difficult to
maintain, this rework is used as an opportunity to finally group functions
into separate files, as in mlx5.

This rework targets DPDK 17.11.
