Subject: net: cxgb4vf: reject unsupported coalescing params
Patch-mainline: v5.7-rc1
Git-commit: 009ab69b4b679d0e7d75a454c9b056b4883bbfee
References: jsc#SLE-15131

Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.

This driver did not previously reject unsupported parameters.
