[PATCH net-next v2 6/9] eth: fwnode: remove the addr len from mac helpers
From: Jakub Kicinski <kuba@kernel.org>

Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Timur Tabi, Steve Glendinning, Ilias Apalodimas, Masahisa Kojima, Linus Torvalds
All callers pass in ETH_ALEN and the function itself will return -EINVAL for any other address length. Just assume it's ETH_ALEN like all other mac address helpers (nvm, of, platform).
