[GIT PULL] Networking

[Jakub Kicinski <kuba@kernel.org>]

Hi Linus!

Latest fixes from the networking tree. Experimenting with the format 
of the description further, I'll find out if you liked it based on how 
it ends up looking in the tree :)

The following changes since commit 9ff9b0d392ea08090cd1780fb196f36dbb586529:

  Merge tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next (2020-10-15 18:42:13 -0700)

  tcp: fix to update snd_wl1 in bulk receiver fast path (2020-10-22 12:26:57 -0700)

----------------------------------------------------------------
Fixes for 5.10-rc1 from the networking tree:

Cross-tree/merge window issues:

 - rtl8150: don't incorrectly assign random MAC addresses; fix late
   in the 5.9 cycle started depending on a return code from
   a function which changed with the 5.10 PR from the usb subsystem

Current release - regressions:

 - Revert "virtio-net: ethtool configurable RXCSUM", it was causing
   crashes at probe when control vq was not negotiated/available

Previous releases - regressions:

 - ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
   bus, only first device would be probed correctly

 - nexthop: Fix performance regression in nexthop deletion by
   effectively switching from recently added synchronize_rcu()
   to synchronize_rcu_expedited()

 - netsec: ignore 'phy-mode' device property on ACPI systems;
   the property is not populated correctly by the firmware,
   but firmware configures the PHY so just keep boot settings

Previous releases - always broken:

 - tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
   bulk transfers getting "stuck"

 - icmp: randomize the global rate limiter to prevent attackers from
   getting useful signal

 - r8169: fix operation under forced interrupt threading, make the
   driver always use hard irqs, even on RT, given the handler is
   light and only wants to schedule napi (and do so through
   a _irqoff() variant, preferably)

 - bpf: Enforce pointer id generation for all may-be-null register
   type to avoid pointers erroneously getting marked as null-checked

 - tipc: re-configure queue limit for broadcast link

 - net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
   tunnels

 - fix various issues in chelsio inline tls driver

Misc:

 - bpf: improve just-added bpf_redirect_neigh() helper api to support
   supplying nexthop by the caller - in case BPF program has already
   done a lookup we can avoid doing another one

 - remove unnecessary break statements

 - make MCTCP not select IPV6, but rather depend on it
