Subject: [PATCH net-next 01/11] arch: use eth_hw_addr_set()

From: Jakub Kicinski <[email-masked]>

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Convert misc arch drivers from memcpy(... ETH_ADDR) to eth_hw_addr_set():

  expression dev, np;
  @@
  - memcpy(dev->dev_addr, np, ETH_ALEN)
  + eth_hw_addr_set(dev, np)
