[dpdk-dev] [PATCH 00/23] net/sfc: support equal stride super-buffer Rx mode

[Andrew Rybchenko]

Add support for dedicated DPDK firmware variant which has equal stride
super-buffer Rx mode. The Rx mode uses bucket mempool manager which
supports allocation of contiguos block of mbufs.

It allows to achieve higher packet rate on Rx than traditional single
packet Rx mode.

Also the Rx mode supports rte_flow MARK and FLAG actions.

It should be applied on top of [1], [2], [3], [4], [5].

There are a number of known checkpatches.sh warnings in base driver due
to coding style difference and in the PMD itself due to postive errno
used inside the driver.
