[dpdk-dev] [PATCH v2 0/3] AF_XDP tx halt fix, IRQ pinning and unaligned chunks

[Ciara Loftus <ciara.loftus@intel.com>]

This series contains 3 patches for the AF_XDP PMD.

Previous: http://mails.dpdk.org/archives/dev/2019-September/143910.html

Patch 1: fix Tx halt when no recv packets (Xiaolong Ye)

Patch 2: support pinning of IRQs
v1 -> v2:
* Change enum format to match coding style
* Change some variables to const
* Re-order arguments in functions
* Do not duplicate driver string in generate_search_idx
* Check if driver handler function ptr is !NULL before using
* Check return value of fwrite
* Use rte_memcpy

Patch 3: enable support for unaligned umem chunks
v1 -> v2:
* Take mbuf alloc out of reserve_fill_queue
* Free correct mbuf on reserve fail for tx

The performance of the new zero copy implementation was measured to be within 5%
of the previous zero copy implementation, generally with an improvement observed
for single-core (with need wakeup) and multiple-PMD test cases.
