[dpdk-dev] [PATCH v2 11/13] net/mlx5: remove ibv_* dependency in Rx/Tx objects

[Ophir Munk <ophirmu@nvidia.com>]

From: Ophir Munk <ophirmu@mellanox.com>

Replace pointers to ibv structs with pointers to void (file
mlx5_rxtx.h).  Specifically the following pointers were replaced:
'struct ibv_cq *', 'struct ibv_wq *', 'struct ibv_comp_channel *',
'struct ibv_rwq_ind_table *a', 'struct ibv_qp *'.
