Subject: [PATCH net] etherdevice: use __dev_addr_set()
Date: Mon, 4 Oct 2021 16:01:40 -0700 [thread overview]
Message-ID: <20211004230140.2547271-1-kuba@kernel.org> (raw)
Andrew points out that eth_hw_addr_set() replaces memcpy()
calls so we can't use ether_addr_copy() which assumes
both arguments are 2-bytes aligned.
