Subject: [PATCH net-next 3/9] net: dwc-xlgmac: let core reject the unsupported coalescing parameters
Date: Mon, 16 Mar 2020 13:47:06 -0700 [thread overview]
Message-ID: <20200316204712.3098382-4-kuba@kernel.org> (raw)
In-Reply-To: <20200316204712.3098382-1-kuba@kernel.org>
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.
This driver already correctly rejected all unsupported
parameters.
While at it remove unnecessary zeroing on get.
No functional changes.
