[dpdk-dev] [PATCH v2 3/3] net/mlx5: rebuild flows on updating RETA

[Yongseok Koh <yskoh@mellanox.com>]

Currently mlx5_dev_rss_reta_update() just updates tables in the host,
therefore it isn't immediately effective until restarting the device by
calling mlx5_dev_stop()/mlx5_dev_start() to update the changes in the
device side. This patch adds rebuilding the device-specific datastructure
and applying it to the device right away.
