Subject: [PATCH 1/2] net: tg3: reject unsupported coalescing params
Git-commit: 3eb2efbea193789397c36f52b17d8692ac79bf68
Patch-mainline: v5.7-rc1
References: jsc#SLE-14859
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.
This driver did not previously reject unsupported parameters.
