[dpdk-dev] [PATCH v1 15/15] net/mlx5: remove Rx queue object type field

[Michael Baum <michaelba@nvidia.com>]

Once the separation between Verbs and DevX is done using function
pointers, the type field of the Rx queue object structure becomes
redundant and no more code is used.
Remove the unnecessary field from the structure.
