Subject: net: ethtool: Make helpers public
Patch-mainline: v5.8-rc1
Git-commit: 0df960f14e17e55e68dfd1342f063d17dbcc6107
References: bsc#1176447

Make some helpers for building ethtool netlink messages available
outside the compilation unit, so they can be used for building
messages which are not simple get/set.
