Series ethtool: consolidate irq coalescing - other drivers | expand

Commit Message

Jakub Kicinski March 6, 2020, 1:06 a.m. UTC
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.

This driver correctly rejects all unsupported parameters.
As a side effect of these changes the error code for
unsupported params changes from EINVAL to EOPNOTSUPP.
