Pull networking fixes from David Miller:

 1) Lots more phydev and probe error path leaks in various drivers by
    Johan Hovold.

 2) Fix race in packet_set_ring(), from Philip Pettersson.

 3) Use after free in dccp_invalid_packet(), from Eric Dumazet.

 4) Signnedness overflow in SO_{SND,RCV}BUFFORCE, also from Eric
    Dumazet.

 5) When tunneling between ipv4 and ipv6 we can be left with the wrong
    skb->protocol value as we enter the IPSEC engine and this causes all
    kinds of problems. Set it before the output path does any
    dst_output() calls, from Eli Cooper.

 6) bcmgenet uses wrong device struct pointer in DMA API calls, fix from
    Florian Fainelli.

 7) Various netfilter nat bug fixes from FLorian Westphal.

 8) Fix memory leak in ipvlan_link_new(), from Gao Feng.

 9) Locking fixes, particularly wrt. socket lookups, in l2tp from
    Guillaume Nault.

10) Avoid invoking rhash teardowns in atomic context by moving netlink
    cb->done() dump completion from a worker thread. Fix from Herbert
    Xu.

11) Buffer refcount problems in tun and macvtap on errors, from Jason
    Wang.

12) We don't set Kconfig symbol DEFAULT_TCP_CONG properly when the user
    selects BBR. Fix from Julian Wollrath.

13) Fix deadlock in transmit path on altera TSE driver, from Lino
    Sanfilippo.

14) Fix unbalanced reference counting in dsa_switch_tree, from Nikita
    Yushchenko.

15) tc_tunnel_key needs to be properly exported to userspace via uapi,
    fix from Roi Dayan.

16) rds_tcp_init_net() doesn't unregister notifier in error path, fix
    from Sowmini Varadhan.

17) Stale packet header pointer access after pskb_expand_head() in
    genenve driver, fix from Sabrina Dubroca.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (103 commits)

@ -9,10 +9,26 @@ The following properties are common to the Ethernet controllers:
- max-speed: number, specifies maximum speed in Mbit/s supported by the device;
- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than
the maximum frame size (there's contradiction in ePAPR).
- phy-mode: string, operation mode of the PHY interface; supported values are
"mii", "gmii", "sgmii", "qsgmii", "tbi", "rev-mii", "rmii", "rgmii", "rgmii-id",
"rgmii-rxid", "rgmii-txid", "rtbi", "smii", "xgmii", "trgmii"; this is now a
de-facto standard property;
- phy-mode: string, operation mode of the PHY interface. This is now a de-facto
standard property; supported values are:
* "mii"
* "gmii"
* "sgmii"
* "qsgmii"
* "tbi"
* "rev-mii"
* "rmii"
* "rgmii" (RX and TX delays are added by the MAC when required)
* "rgmii-id" (RGMII with internal RX and TX delays provided by the PHY, the
MAC should not add the RX or TX delays in this case)
* "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC
should not add an RX delay in this case)
* "rgmii-txid" (RGMII with internal TX delay provided by the PHY, the MAC
should not add an TX delay in this case)
* "rtbi"
* "smii"
* "xgmii"
* "trgmii"
- phy-connection-type: the same as "phy-mode" property but described in ePAPR;
- phy-handle: phandle, specifies a reference to a node representing a PHY
device; this property is described in ePAPR and so preferred;
