[net-next 09/15] net/mlx5e: Use tc sample stubs instead of ifdefs in source file
From: Saeed Mahameed <saeed@kernel.org>
Date: 2021-09-02 19:06:34
Subsystem:
mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:

From: Roi Dayan <redacted> Instead of having sparse ifdefs in source files use a single ifdef in the tc sample header file and use stubs.
