[PATCH mlx5-next 07/17] net/mlx5: Merge various control path IPsec headers into one file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Leon Romanovsky <leonro@xxxxxxxxxx>

The mlx5 IPsec code has logical separation between code that operates
with XFRM objects (ipsec.c), HW objects (ipsec_offload.c), flow steering
logic (ipsec_fs.c) and data path (ipsec_rxtx.c).

Such separation makes sense for C-files, but isn't needed at all for
H-files as they are included in batch anyway.
