From 987b191c16f9b7568a756b0745ee4a93611879ae Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 4 Mar 2020 21:15:36 -0800 Subject: [PATCH] ionic: 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. As a side effect of these changes the error code for unsupported params changes from EINVAL to EOPNOTSUPP. v3: adjust commit message for new error code and member name Signed-off-by: Jakub Kicinski Acked-by: Shannon Nelson Signed-off-by: David S.
