Subject: [PATCH net-next 03/12] enic: let core reject the unsupported coalescing parameters
Date: Tue,  3 Mar 2020 19:54:52 -0800	[thread overview]
Message-ID: <20200304035501.628139-4-kuba@kernel.org> (raw)
In-Reply-To: <20200304035501.628139-1-kuba@kernel.org>

Set ethtool_ops->coalesce_types to let the core reject
unsupported coalescing parameters.

This driver correctly rejects all unsupported parameters.
No functional changes.
