Subject: net/mlx5: fix misplaced Rx interrupts functions
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b18042fb8f49b805579136f748cfe29e0cf18d25;p=dpdk.git

net/mlx5: fix misplaced Rx interrupts functions

These functions do not belong to the data path. Their prototypes are also
misplaced.

Fixes: 3c7d44af252a ("net/mlx5: support user space Rx interrupt event")
