Subject: net: mlx4: reject unsupported coalescing params
Patch-mainline: v5.7-rc1
Git-commit: bd4be35b4ae2c218348852a163a0dabba0d4228c
References: jsc#SLE-15171
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.
This driver did not previously reject unsupported parameters.
