Pull networking fixes from David Miller:

 1) Fix up several Kconfig dependencies in netfilter, from Martin Willi
    and Florian Westphal.

 2) Memory leak in be2net driver, from Petr Oros.

 3) Memory leak in E-Switch handling of mlx5 driver, from Raed Salem.

 4) mlx5_attach_interface needs to check for errors, from Huy Nguyen.

 5) tipc_release() needs to orphan the sock, from Cong Wang.

 6) Need to program TxConfig register after TX/RX is enabled in r8169
    driver, not beforehand, from Maciej S. Szmigiero.

 7) Handle 64K PAGE_SIZE properly in ena driver, from Netanel Belgazal.

 8) Fix crash regression in ip_do_fragment(), from Taehee Yoo.

 9) syzbot can create conditions where kernel log is flooded with
    synflood warnings due to creation of many listening sockets, fix
    that. From Willem de Bruijn.

10) Fix RCU issues in rds socket layer, from Cong Wang.

11) Fix vlan matching in nfp driver, from Pieter Jansen van Vuuren.

This option adds a `CHECKSUM' target, which can be used in the iptables mangle
table.
table to work around buggy DHCP clients in virtualized environments.
You can use this target to compute and fill in the checksum in
a packet that lacks a checksum. This is particularly useful,
if you need to work around old applications such as dhcp clients,
that do not work well with checksum offloads, but don't want to disable
checksum offload in your device.
Some old DHCP clients drop packets because they are not aware
that the checksum would normally be offloaded to hardware and
thus should be considered valid.
This target can be used to fill in the checksum using iptables
when such packets are sent via a virtual network device.
To compile it as a module, choose M here. If unsure, say N.
