GIT bisecting the lockdep problem is surely going the land you on:

commit e308a5d806c852f56590ffdd3834d0df0cbed8d7

netdev: Add netdev->addr_list_lock protection.

Add netif_addr_{lock,unlock}{,_bh}() helpers.

Use them to protect operations that operate on or read
the network device unicast and multicast address lists.

Also use them in cases where the code simply wants to
block calls into the driver's ->set_rx_mode() and
->set_multicast_list() methods.
