[dpdk-dev] [PATCH v2 1/5] mlx5: refactor special flows handling

Adrien Mazarguil adrien.mazarguil at 6wind.com
Mon Feb 22 19:02:03 CET 2016


From: Yaacov Hazan <yaacovh at mellanox.com>

Merge redundant code by adding a static initialization table to manage
promiscuous and allmulticast (special) flows.

New function priv_rehash_flows() implements the logic to enable/disable
relevant flows in one place from any context.
