Ido Schimmel says:

====================
mlxsw: Enable MC-aware mode for mlxsw ports

Petr says:

Due to an issue in Spectrum chips, when unicast traffic shares the same
queue as BUM traffic, and there is a congestion, the BUM traffic is
admitted to the queue anyway, thus pushing out all UC traffic. In order
to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.

Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8. That
limits the number of available TCs, but since mlxsw currently only uses
the lower eight anyway, it is no real loss.

The two TCs (UC and MC one) are then mapped to the same subgroup and
strictly prioritized so that UC traffic is preferred in case of
congestion.

In patch #1, introduce a new register, QTCTM, which enables the
multicast-aware mode.

In patch #2, fix a typo in related code.

In patch #3, set up TCs and QTCTM to enable multicast-aware mode.

7b81953066 mlxsw: spectrum: Configure MC-aware mode on mlxsw ports
In order to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.

Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8.

ETS elements for TCs 8..15 thus need to be configured as well. Extend
mlxsw_sp_port_ets_init() so that it maps each of them to the same
subgroup as their corresponding TC from the range 0..7, such that TCs X
and X+8 map to the same subgroup.

The existing code configures TCs with strict priority. So far this was
immaterial, because each TC had its own subgroup. Now that two TCs share
a subgroup it becomes important. TCs are prioritized in order of 7, 6,
..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being
deprioritized. Since that's what's needed, keep that configuration as it
is, and configure the new TCs likewise.

Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to
enable MC-aware mode on each port.

0ed4229b08 ipv6: defrag: drop non-last frags smaller than min mtu
don't bother with pathological cases, they only waste cycles.
IPv6 requires a minimum MTU of 1280 so we should never see fragments
smaller than this (except last frag).

v3: don't use awkward "-offset + len"
v2: drop IPv4 part, which added same check w. IPV4_MIN_MTU (68).
    There were concerns that there could be even smaller frags
    generated by intermediate nodes, e.g. on radio networks.

added external phy loopback test and phy setup retry logic that is

new VF resource allocation mode that requires the VF driver to
reserve resources during IFUP.  IF state changes are now propagated
to firmware so that firmware can release some resources during IFDOWN.

ethtool method to get firmware core dump and hwmon temperature reading
have been added.  DSCP to user priority support has been added to
the driver's DCBNL interface, and the CoS queue logic has been refined
to make sure that the special RDMA Congestion Notification hardware CoS
queue will not be used for networking traffic.

Use latest firmware API to notify firmware about IF state changes.
Firmware has the option to clean up resources during IF down and
to require the driver to reserve resources again during IF up.

50f011b63d bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.
Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the
firmware that the driver is compliant with the latest spec.  With
that, the firmware can return expanded RSS profile IDs that the driver
checks to setup the proper gso_type for GRO-HW packets.  But instead
of checking for the new profile IDs, we check the IP_TYPE flag
in TPA_START which is more straight forward than checking a list of
profile IDs.

bf82736da3 bnxt_en: Add new VF resource allocation strategy mode.
The new mode is "minimal-static" to be used when resources are more
limited to support a large number of VFs, for example  The PF driver
will provision guaranteed minimum resources of 0.  Each VF has no
guranteed resources until it tries to reserve resources during device
open.

During hotplug, the driver's open function can be called almost
immediately after power on reset.  The PHY may not be ready and the
firmware may return failure when the driver tries to update PHY
settings.  Add retry logic fired from the driver's timer to retry
the operation for 5 seconds.

e795892e93 bnxt_en: Adjust timer based on ethtool stats-block-usecs settings.
The driver gathers statistics using 2 mechanisms.  Some stats are DMA'ed
directly from hardware and others are polled from the driver's timer.
Currently, we only adjust the DMA frequency based on the ethtool
stats-block-usecs setting.  This patch adjusts the driver's timer
frequency as well to make everything consistent.

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next tree:

1) Support for transparent proxying for nf_tables, from Mate Eckl.

2) Patchset to add OS passive fingerprint recognition for nf_tables,
   from Fernando Fernandez. This takes common code from xt_osf and
   place it into the new nfnetlink_osf module for codebase sharing.

3) Lightweight tunneling support for nf_tables.

4) meta and lookup are likely going to be used in rulesets, make them
   direct calls. From Florian Westphal.

A bunch of incremental updates:

5) use PTR_ERR_OR_ZERO() from nft_numgen, from YueHaibing.

6) Use kvmalloc_array() to allocate hashtables, from Li RongQing.

7) Explicit dependencies between nfnetlink_cttimeout and conntrack
   timeout extensions, from Harsha Sharma.

8) Simplify NLM_F_CREATE handling in nf_tables.

9) Removed unused variable in the get element command, from
   YueHaibing.

10) Expose bridge hook priorities through uapi, from Mate Eckl.

And a few fixes for previous Netfilter batch for net-next:

11) Use per-netns mutex from flowtable event, from Florian Westphal.

12) Remove explicit dependency on iptables CT target from conntrack
    zones, from Florian.

13) Fix use-after-free in rmmod nf_conntrack path, also from Florian.
