Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
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.
