Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) GTP fixes from Andreas Schultz (missing genl module alias, clear IP
DF on transmit).
2) Netfilter needs to reflect the fwmark when sending resets, from Pau
Espin Pedrol.
3) nftable dump OOPS fix from Liping Zhang.
4) Fix erroneous setting of VIRTIO_NET_HDR_F_DATA_VALID on transmit,
from Rolf Neugebauer.
5) Fix build error of ipt_CLUSTERIP when procfs is disabled, from Arnd
Bergmann.
6) Fix regression in handling of NETIF_F_SG in harmonize_features(),
from Eric Dumazet.
7) Fix RTNL deadlock wrt. lwtunnel module loading, from David Ahern.
8) tcp_fastopen_create_child() needs to setup tp->max_window, from
Alexey Kodanev.
9) Missing kmemdup() failure check in ipv6 segment routing code, from
Eric Dumazet.
10) Don't execute unix_bind() under the bindlock, otherwise we deadlock
with splice. From WANG Cong.
11) ip6_tnl_parse_tlv_enc_lim() potentially reallocates the skb buffer,
therefore callers must reload cached header pointers into that skb.
Fix from Eric Dumazet.
12) Fix various bugs in legacy IRQ fallback handling in alx driver, from
Tobias Regnery.
13) Do not allow lwtunnel drivers to be unloaded while they are
referenced by active instances, from Robert Shearman.
14) Fix truncated PHY LED trigger names, from Geert Uytterhoeven.
15) Fix a few regressions from virtio_net XDP support, from John
Fastabend and Jakub Kicinski.
