Pull networking fixes from David Miller:
1) L2TP doesn't get autoloaded when you try to open an L2TP socket due
to a missing module alias, fix from Benjamin LaHaise.
2) Netlabel and RDS should propagate gfp flags given to them by
callers, fixes from Dan Carpeneter.
3) Recursive locking fix in usbnet wasn't bulletproof and can result in
objects going away mid-flight due to races, fix from Ming Lei.
4) Fix up some confusion about a bool module parameter in netfilter's
iptable_filter and ip6table_filter, from Rusty Russell.
5) If SKB recycling is used via napi_reuse_skb() we end up with
different amounts of headroom reserved than we had at the original
SKB allocation. Fix from Eric Dumazet.
6) Fix races in TG3 driver ring refilling, from Michael Chan.
7) We have callbacks for IPSEC replay notifiers, but some call sites
were not using the ops method and instead were calling one of the
implementations directly. Oops. Fix from Steffen Klassert.
8) Fix IP address validation properly in the bonding driver, the
previous fix only works with netlink where the subnet mask and IP
address are changed in one atomic operation. When 'ifconfig' ioctls
are used the IP address and the subnet mask are changed in two
distinct operations. Fix from Andy Gospodarek.
9) Provide a sky2 module operation to work around power management
issues with some BIOSes. From Stephen Hemminger.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
usbnet: consider device busy at each recieved packet
bonding: remove entries for master_ip and vlan_ip and query devices instead
netfilter: remove forward module param confusion.
usbnet: don't clear urb->dev in tx_complete
usbnet: increase URB reference count before usb_unlink_urb
xfrm: Access the replay notify functions via the registered callbacks
xfrm: Remove unused xfrm_state from xfrm_state_check_space
RDS: use gfp flags from caller in conn_alloc()
netlabel: use GFP flags from caller instead of GFP_ATOMIC
l2tp: enable automatic module loading for l2tp_ppp
cnic: Fix parity error code conflict
tg3: Fix RSS ring refill race condition
sky2: override for PCI legacy power management
net: fix napi_reuse_skb() skb reserve
