From 4a1ce0107e092d7701a8c186c1b4957e7c46d93a Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 4 Mar 2020 21:15:32 -0800 Subject: [PATCH] xgbe: 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. We are only losing the error print. v3: adjust commit message for new error code and member name Signed-off-by: Jakub Kicinski Acked-by: Tom Lendacky Signed-off-by: David S.
