From 8213f6c9a275da084dc9363f36f93138547f46f1 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 11 Mar 2020 15:32:48 -0700 Subject: [PATCH] net: be2net: reject unsupported coalescing params Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver did not previously reject unsupported parameters. Signed-off-by: Jakub Kicinski Signed-off-by: David S.
