Subject: net/mlx5e: IPoIB, Move to a separate directory
Patch-mainline: v4.13-rc1
Git-commit: 4301ba7b3ed9d3ffbaebc295413fcd3e8ab34949
References: bsc#1046303 FATE#322944

IPoIB netdevice driver was only introduced in previous kernel release
and it is growing in terms of features and LOC, move it to a separate
directory.
