From: Saeed Mahameed <saeed@kernel.org>

Subsystem:
mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:

From: Aya Levin <redacted> Support RQ activation for RQs without an ICOSQ in the main flow, like existing trap-RQ and like PTP-RQ that will be introduced in the coming patches in the patchset. With this patch, remove the wrapper in traps to deactivate the trap-RQ.
