[PATCH 08/15] wireless: cisco: use eth_hw_addr_set()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Use dev_addr_set() to match the existing logic.
setup_card() is always passed netdev->dev_addr, so pass the netdev
pointer instead and assign the address using a helper there.
