Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) The per-network-namespace loopback device, and thus its namespace, can have its teardown deferred for a long time if a kernel created TCP socket closes and the namespace is exiting meanwhile. The kernel keeps trying to finish the close sequence until it times out (which takes quite some time). Fix this by forcing the socket closed in this situation, from Dan Streetman. 2) Fix regression where we're trying to invoke the update_pmtu method on route types (in this case metadata tunnel routes) that don't implement the dst_ops method. Fix from Nicolas Dichtel. 3) Fix long standing memory corruption issues in r8169 driver by performing the chip statistics DMA programming more correctly. From Francois Romieu. 4) Handle local broadcast sends over VRF routes properly, from David Ahern. 5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket can never be released. From Alexey Kodanev. 6) Set poll flags properly in VSOCK protocol layer, from Stefan Hajnoczi. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: set POLLOUT | POLLWRNORM for TCP_CLOSING dccp: don't restart ccid2_hc_tx_rto_expire() if sk in closed state net: vrf: Add support for sends to local broadcast address r8169: fix memory corruption on retrieval of hardware statistics. net: don't call update_pmtu unconditionally net: tcp: close sock if net namespace is exiting
