[dpdk-dev] [PATCH v4 4/4] net/mlx5: move locally used functions to static

[Dekel Peled <dekelp@mellanox.com>]

Multiple functions were declared in header file mlx5_rxtx.h,
inplemented in mlx5_rxq.c, and called only in mlx5_rxq.c.

This patch moves all these functions declarations into mlx5_rxq.c,
as static functions.
Some functions implementation was copied higher in the file to
precede the functions calls.
