Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/usb/asix_common.c drivers/net/usb/sr9800.c drivers/net/usb/usbnet.c include/linux/usb/usbnet.h net/ipv4/tcp_ipv4.c net/ipv6/tcp_ipv6.c The TCP conflicts were overlapping changes. In 'net' we added a READ_ONCE() to the socket cached RX route read, whilst in 'net-next' Eric Dumazet touched the surrounding code dealing with how mini sockets are handled. With USB, it's a case of the same bug fix first going into net-next and then I cherry picked it back into net. Signed-off-by: David S. Miller <davem@davemloft.net>
