Subject: [PATCH net-next v3 03/12] enic: let core reject the unsupported coalescing parameters
Date: Wed, 4 Mar 2020 21:15:33 -0800 [thread overview]
Message-ID: <20200305051542.991898-4-kuba@kernel.org> (raw)
In-Reply-To: <20200305051542.991898-1-kuba@kernel.org>
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.
This driver correctly rejects all unsupported parameters.
The error code changes from EINVAL to EOPNOTSUPP.
v3: adjust commit message for new error code and member name
