From 6427477136207bd6cb6e71a4167b2a2efa3f56e9 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 12 Mar 2020 21:07:58 -0700 Subject: [PATCH] net: netxen: let core reject the unsupported coalescing parameters Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. As a side effect of these changes the error code for unsupported params changes from EINVAL to EOPNOTSUPP. The driver was missing a check for rate_sample_interval.
