[dpdk-dev] [PATCH v3 1/4] net/mlx5: remove unused functions

[Dekel Peled]

Functions implemented but never called:
mlx5_rxq_ibv_releasable()
mlx5_rxq_cleanup()
mlx5_txq_ibv_releasable()

Function declared but not implemented:
rxq_alloc_mprq_buf()

This patch removes these functions from code and header file.
