Subject: net: iavf: reject unsupported coalescing params
Patch-mainline: v5.7-rc1
Git-commit: cf5d0f1c24b1aa23f84983adacfeab3365ce2cc8
References: jsc#SLE-12877
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.
This driver did not previously reject unsupported parameters.
