Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:
 "This set fixes a bunch of fallout from the changes that went in during
  this merge window, particularly:

   - Fix fsl_pq_mdio (Claudiu Manoil) and fm10k (Pranith Kumar) build
     failures.

   - Several networking drivers do atomic_set() on page counts where
     that's not exactly legal.  From Eric Dumazet.

   - Make __skb_flow_get_ports() work cleanly with unaligned data, from
     Alexander Duyck.

   - Fix some kernel-doc buglets in rfkill and netlabel, from Fabian
     Frederick.

   - Unbalanced enable_irq_wake usage in bcmgenet and systemport
     drivers, from Florian Fainelli.

   - pxa168_eth needs to depend on HAS_DMA, from Geert Uytterhoeven.

   - Multi-dequeue in the qdisc layer severely bypasses the fairness
     limits the previous code used to enforce, reintroduce in a way that
     at the same time doesn't compromise bulk dequeue opportunities.
     From Jesper Dangaard Brouer.

   - macvlan receive path unnecessarily hops through a softirq by using
     netif_rx() instead of netif_receive_skb().  From Jason Baron"
