Subject: Re: [PATCH] net: Correctly sync addresses from multiple sources to
 single device

I applied this to net-next since 3.13 just got released, and it doesn't

net/core/dev_addr_lists.c: In function ‘__hw_addr_sync_one’:
net/core/dev_addr_lists.c:144:26: error: ‘struct netdev_hw_addr’ has no member named ‘sync_count’
