From 812df69beb86b0e6decbb109ee3fa408dcb7fa5d Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 9 Mar 2020 19:15:06 -0700 Subject: net: liquidio: 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.
