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.
