From eff87b4f1ef46f5a2a6043011f81a472e0eec112 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 16 Mar 2020 13:47:04 -0700 Subject: net: sfc: 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. The check for use_adaptive_tx_coalesce will now be done by the core.
