From 0e72ea19e395554d3b8c54806720fe8e7a18939c Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 4 Mar 2020 21:15:35 -0800 Subject: [PATCH] nfp: let core reject the unsupported coalescing parameters Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver correctly rejects all unsupported parameters. No functional changes. v3: adjust commit message for new error code and member name Signed-off-by: Jakub Kicinski Signed-off-by: David S.
