In the commit referenced below, hw_stats_type of an entry is set for every
entry that corresponds to a pedit action. However, the assignment is only
done after the entry pointer is bumped, and therefore could overwrite
memory outside of the entries array.
The reason for this positioning may have been that the current entry's
hw_stats_type is already set above, before the action-type dispatch.
However, if there are no more actions, the assignment is wrong. And if
there are, the next round of the for_each_action loop will make the
assignment before the action-type dispatch anyway.
Therefore fix this issue by simply reordering the two lines.

Chelsio NICs have 3 filter regions, in following order of priority:

2. HASH region.
3. Normal FILTER region (Lowest Priority).
Currently, there's a 1-to-1 mapping between the prio value passed

multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the

s390/qeth: balance the TX queue selection for IQD devices
For ucast traffic, qeth_iqd_select_queue() falls back to
netdev_pick_tx(). This will potentially use skb_tx_hash() to distribute
the flow over all active TX queues - so txq 0 is a valid selection, and
qeth_iqd_select_queue() needs to check for this and put it on some other
queue. As a result, the distribution for ucast flows is unbalanced and
hits QETH_IQD_MIN_UCAST_TXQ heavier than the other queues.
Open-coding a custom variant of skb_tx_hash() isn't an option, since
netdev_pick_tx() also gives us eg. access to XPS. But we can pull a
little trick: add a single TC class that excludes the mcast txq, and
thus encourage skb_tx_hash() to not pick the mcast txq.

Similar to the support for z/VM NICs, but we need to take extra care

mcast txq. Catch this.
2. require at least _two_ TX queues - one for ucast, one for mcast.
3. when reducing the number of TX queues, there's a potential race
where netdev_cap_txqueue() over-rules the selected txq index and
falls back to index 0. This would place ucast traffic on the mcast
queue, and result in TX errors.

====================
net: bridge: vlan options: add support for tunnel mapping
In order to bring the new vlan API on par with the old one and be able
to completely migrate to the new one we need to support vlan tunnel mapping
and statistics. This patch-set takes care of the former by making it a
vlan option. There are two notable issues to deal with:
- vlan range to tunnel range mapping
* The tunnel ids are globally unique for the vlan code and a vlan can
be mapped to one tunnel, so the old API took care of ranges by
taking the starting tunnel id value and incrementally mapping
vlan id(i) -> tunnel id(i). This set takes the same approach and
uses one new attribute - BRIDGE_VLANDB_ENTRY_TUNNEL_ID. If used
with a vlan range then it's the starting tunnel id to map.
- tunnel mapping removal
* Since there are no reserved/special tunnel ids defined, we can't
encode mapping removal within the new attribute, in order to be
able to remove a mapping we add a vlan flag which makes the new
tunnel option remove the mapping
The rest is pretty straight-forward, in fact we directly re-use the old
code for manipulating tunnels by just mapping the command (set/del). In
order to be able to keep detecting vlan ranges we check that the current
vlan has a tunnel and it's extending the current vlan range end's tunnel
id.

net: bridge: vlan options: add support for tunnel mapping set/del
This patch adds support for manipulating vlan/tunnel mappings. The
tunnel ids are globally unique and are one per-vlan. There were two
trickier issues - first in order to support vlan ranges we have to
compute the current tunnel id in the following way:
- base tunnel id (attr) + current vlan id - starting vlan id
This is in line how the old API does vlan/tunnel mapping with ranges. We
already have the vlan range present, so it's redundant to add another
attribute for the tunnel range end. It's simply base tunnel id + vlan
range. And second to support removing mappings we need an out-of-band way
to tell the option manipulating function because there are no
special/reserved tunnel id values, so we use a vlan flag to denote the
operation is tunnel mapping removal.

Add a new option - BRIDGE_VLANDB_ENTRY_TUNNEL_ID which is used to dump

range map simply as: vlan range end id - vlan range start id. The
starting point is the tunnel id in BRIDGE_VLANDB_ENTRY_TUNNEL_ID. This
is similar to how the tunnel entries can be created in a range via the
old API (a vlan range maps to a tunnel range).

Add a new attribute to control the fq qdisc hrtimer slack.
Default is set to 10 usec.
When/if packets are throttled, fq set up an hrtimer that can
lead to one interrupt per packet in the throttled queue.
By using a timer slack, we allow better use of timer interrupts,
by giving them a chance to call multiple timer callbacks
at each hardware interrupt.
Also, giving a slack allows FQ to dequeue batches of packets
instead of a single one, thus increasing xmit_more efficiency.
This has no negative effect on the rate a TCP flow can sustain,
since each TCP flow maintains its own precise vtime (tp->tcp_wstamp_ns)

1000 concurrent flows all using paced packets.
1,000,000 packets sent per second.

net/mlx5e: Fix devlink port register sequence
If udevd is configured to rename interfaces according to persistent
naming rules and if a network interface has phys_port_name in sysfs,
its contents will be appended to the interface name.
However, register_netdev creates device in sysfs and if
devlink_port_register is called after that, there is a timeframe in
which udevd may read an empty phys_port_name value. The consequence is
that the interface will lose this suffix and its name will not be
really persistent.
The solution is to register the port before registering a netdev.

netfilter: Introduce egress hook
Commit
e687ad60af09 ("netfilter: add netfilter ingress hook after
handle_ing() under unique static key") introduced the ability to
classify packets on ingress.
Allow the same on egress. Position the hook immediately before a packet
is handed to tc and then sent out on an interface, thereby mirroring the
ingress order. This order allows marking packets in the netfilter
egress hook and subsequently using the mark in tc. Another benefit of
this order is consistency with a lot of existing documentation which
says that egress tc is performed after netfilter hooks.
Egress hooks already exist for the most common protocols, such as
NF_INET_LOCAL_OUT or NF_ARP_OUT, and those are to be preferred because
they are executed earlier during packet processing. However for more
exotic protocols, there is currently no provision to apply netfilter on
egress. A common workaround is to enslave the interface to a bridge and
use ebtables, or to resort to tc. But when the ingress hook was
introduced, consensus was that users should be given the choice to use
netfilter or tc, whichever tool suits their needs best:
https://lore.kernel.org/netdev/
20150430153317.GA3230@salvia/
This hook is also useful for NAT46/NAT64, tunneling and filtering of
locally generated af_packet traffic such as dhclient.
There have also been occasional user requests for a netfilter egress
hook in the past, e.g.:
https://www.spinics.net/lists/netfilter/msg50038.html
