From dbfa497a26e146b9b9401b3c4e8e2ed69ebdd4ad Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 11 Mar 2020 15:33:00 -0700 Subject: [PATCH] net: igc: let core reject the unsupported coalescing parameters Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver was rejecting almost all unsupported parameters already, it was only missing a check for tx_max_coalesced_frames_irq. As a side effect of these changes the error code for unsupported params changes from ENOTSUPP to EOPNOTSUPP. Signed-off-by: Jakub Kicinski Signed-off-by: David S.
