Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Name string overrun fix in gianfar driver from Joe Perches. 2) VHOST bug fixes from Michael S. Tsirkin and Nadav Har'El 3) Fix dependencies on xt_LOG netfilter module, from Pablo Neira Ayuso. 4) Fix RCU locking in xt_CT, also from Pablo Neira Ayuso. 5) Add a parameter to skb_add_rx_frag() so we can fix the truesize adjustments in the drivers that use it. The individual drivers aren't fixed by this commit, but will be dealt with using follow-on commits. From Eric Dumazet. 6) Add some device IDs to qmi_wwan driver, from Andrew Bird. 7) Fix a potential rcu_read_lock() imbalancein rt6_fill_node().
