[dpdk-dev] [PATCH v2 2/7] net/mlx5: fix work queue array size

Indirection table size must be in log to communicate with verbs when the
number of queue is not a power of two, the maximum indirection table size
is use, but not converted to log2.  This makes a memory corruption.

Fixes: 4c7a0f5ff876 ("net/mlx5: make indirection tables shareable")
