Subject: net: igbvf: reject unsupported coalescing params
Patch-mainline: v5.7-rc1
Git-commit: 3ff8000ddc7d940e258dcfd848ee7bc44481a73a
References: jsc#SLE-13536

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

This driver did not previously reject unsupported parameters.
