Subject: [PATCH net-next 01/12] net/mlx5e: Fix aRFS compilation dependency

From: Maor Gottlieb <maorg@...lanox.com>

en_arfs.o should be compiled only if both CONFIG_MLX5_CORE_EN
and CONFIG_RFS_ACCEL are enabled.
Add MLX5_CORE_EN_RFS Kconfig that depends on both of them.

Fixes: 1cabe6b0965e ('net/mlx5e: Create aRFS flow tables')
