[dpdk-dev] [PATCH v2] net/mlx5: fix hashed list size for tunnel flow groups

[Viacheslav Ovsiienko <viacheslavo@nvidia.com>]

The hashed list size must be the power of 2, otherwise the
adjustment is applied and the warning message is emitted.
This patch provides the correct list size to eliminate the
warning.
