[dpdk-dev] [PATCH 0/4] Chained Mbufs support in SW PMDs

[Tomasz Kulasek]

This patch set adds support of scattered-gather list for SW PMDs.

As of now, application needs to reserve continuous block of memory for
mbufs which is not always the case. Hence needed to support chaining of
mbufs which are smaller in size but can be used if chained.

Above work involves:

 a) Create mbuf functions to coalesce mbuf chains into a single mbuf.
 b) For each software poll mode driver code to detect chained mbufs
    support and coalesce these before preforming crypto.
 c) Add relevant unit tests to test the functionality.


Tomasz Kulasek (4):
  rte_mbuf: add rte_pktmbuf_coalesce
  test: add rte_pktmbuf_coalesce unit tests
  crypto: add sgl support for sw PMDs
  test: add sgl unit tests for crypto devices
