Pull networking fixes from David Miller:

1) The forcedeth conversion from pci_*() DMA interfaces to dma_*() ones missed one spot. From Zhu Yanjun.

2) Missing CRYPTO_SHA256 Kconfig dep in cfg80211, from Johannes Berg.

3) Fix checksum offloading in thunderx driver, from Sunil Goutham.

4) Add SPDX to vm_sockets_diag.h, from Stephen Hemminger.

5) Fix use after free of packet headers in TIPC, from Jon Maloy.

6) "sizeof(ptr)" vs "sizeof(*ptr)" bug in i40e, from Gustavo A R Silva.

7) Tunneling fixes in mlxsw driver, from Petr Machata.

8) Fix crash in fanout_demux_rollover() of AF_PACKET, from Mike Maloney.

9) Fix race in AF_PACKET bind() vs. NETDEV_UP notifier, from Eric Dumazet.

10) Fix regression in sch_sfq.c due to one of the timer_setup() conversions. From Paolo Abeni.

11) SCTP does list_for_each_entry() using wrong struct member, fix from Xin Long.

12) Don't use big endian netlink attribute read for IFLA_BOND_AD_ACTOR_SYSTEM, it is in cpu endianness. Also from Xin Long.

13) Fix mis-initialization of q->link.clock in CBQ scheduler, preventing adding filters there. From Jiri Pirko.
