Subject: net: bnx2x: reject unsupported coalescing params
Patch-mainline: v5.7-rc1
Git-commit: a0dadb331dfa33cf7aec77921067be4cf11737ad
References: jsc#SLE-13628

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

This driver did not previously reject unsupported parameters.
