r8152: Support runtime changes of vendor mac passthu policy
On some platforms ACPI method `\\_SB.AMAC` is dynamic and changes to it can
influence changing the behavior of MAC pass through and what MAC address is used.
When running USB reset, re-read the MAC address to use to support tools that
change the policy.
This is quite similar to using `SIOCSIFHWADDR` except that the actual MAC to use
comes from ASL rather than from userspace.
Changes from v1:
* Remove an extra unneeded `ether_addr_copy` call
* Use `dev_set_mac_address` to ensure all notifiers are called
* Shuffle functions to allow code re-use.

In contrast to switching rx irq coalescing off what fixed an issue,
switching tx irq coalescing off is merely a latency optimization,
therefore net-next. As part of this change:
- Remove INTT_0 .. INTT_3 constants, they aren't used.
- Remove comment in rtl_hw_start_8169(), we now have a detailed
description by the code in rtl_set_coalesce().
- Due to switching irq coalescing off per default we don't need the
initialization in rtl_hw_start_8168(). If ethtool is used to switch
on coalescing then rtl_set_coalesce() will configure this register.
For the sake of completeness: This patch just changes the default.
Users still have the option to configure irq coalescing via ethtool.

The merge window for 5.1 introduced a number of compaction-related patches.
with intermittent reports of corruption and functional issues. The bugs
are due to sloopy checking of zone boundaries and a corner case where
invalid indexes are used to access the free lists.
Reports are not common but at least two users and 0-day have tripped
over them. There is a chance that one of the syzbot reports are related
but it has not been confirmed properly.
The normal submission path is with Andrew but there have been some delays
and I consider them urgent enough that they should be picked up before
RC4 to avoid duplicate reports.
All of these have been successfully tested on older RC windows. This
will make this branch look like a rebase but in fact, they've simply
been lifted again from Andrew's tree and placed on a fresh branch. I've
no reason to believe that this has invalidated the testing given the
lack of change in compaction and the nature of the fixes.

The n_r3964 line discipline driver was written in a different time, when

Since then, the world has moved on but not this code, it has stayed
rooted in the past with its lovely hand-crafted list structures and
loads of "interesting" race conditions all over the place.
After attempting to clean up most of the issues, I just gave up and am
now marking the driver as BROKEN so that hopefully someone who has this

and will help with debugging a raft of changes that I had laying around

tipc: improve TIPC unicast link throughput
The series introduces an algorithm to improve TIPC throughput especially
in terms of packet loss, also tries to reduce packet duplication due to
overactive NACK sending mechanism.
The link failover situation is also covered by the patches.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
In commit 0ae955e2656d ("tipc: improve TIPC throughput by Gap ACK
blocks"), we enhance the link transmq by releasing as many packets as
possible with the multi-ACKs from peer node. This also means the queue
is now non-linear and the peer link deferdq becomes vital.
Whereas, in the case of link failover, all messages in the link transmq
need to be transmitted as tunnel messages in such a way that message
sequentiality and cardinality per sender is preserved. This requires us
to maintain the link deferdq somehow, so that when the tunnel messages
arrive, the inner user messages along with the ones in the deferdq will
be delivered to upper layer correctly.
The commit accomplishes this by defining a new queue in the TIPC link
structure to hold the old link deferdq when link failover happens and
process it upon receipt of tunnel messages.
Also, in the case of link syncing, the link deferdq will not be purged
to avoid unnecessary retransmissions that in the worst case will fail
because the packets might have been freed on the sending side.

For unicast transmission, the current NACK sending althorithm is over-
active that forces the sending side to retransmit a packet that is not
really lost but just arrived at the receiving side with some delay, or
even retransmit same packets that have already been retransmitted
before. As a result, many duplicates are observed also under normal
condition, ie. without packet loss.
One example case is: node1 transmits 1 2 3 4 10 5 6 7 8 9, when node2
receives packet #10, it puts into the deferdq. When the packet #5 comes
it sends NACK with gap [6 - 9]. However, shortly after that, when
packet #6 arrives, it pulls out packet #10 from the deferfq, but it is
still out of order, so it makes another NACK with gap [7 - 9] and so on
... Finally, node1 has to retransmit the packets 5 6 7 8 9 a number of
times, but in fact all the packets are not lost at all, so duplicates!
This commit reduces duplicates by changing the condition to send NACK,
also restricting the retransmissions on individual packets via a timer
of about 1ms. However, it also needs to say that too tricky condition
for NACKs or too long timeout value for retransmissions will result in
performance reducing! The criterias in this commit are found to be
effective for both the requirements to reduce duplicates but not affect
performance.
The tipc_link_rcv() is also improved to only dequeue skb from the link
deferdq if it is expected (ie. its seqno <= rcv_nxt).

During unicast link transmission, it's observed very often that because
of one or a few lost/dis-ordered packets, the sending side will fastly
reach the send window limit and must wait for the packets to be arrived
at the receiving side or in the worst case, a retransmission must be
done first. The sending side cannot release a lot of subsequent packets
in its transmq even though all of them might have already been received
by the receiving side.
That is, one or two packets dis-ordered/lost and dozens of packets have
to wait, this obviously reduces the overall throughput!
This commit introduces an algorithm to overcome this by using "Gap ACK
blocks". Basically, a Gap ACK block will consist of <ack, gap> numbers
that describes the link deferdq where packets have been got by the
receiving side but with gaps, for example:
link deferdq: [1 2 3 4 10 11 13 14 15 20]
--> Gap ACK blocks: <4, 5>, <11, 1>, <15, 4>, <20, 0>
The Gap ACK blocks will be sent to the sending side along with the
traditional ACK or NACK message. Immediately when receiving the message
the sending side will now not only release from its transmq the packets
ack-ed by the ACK but also by the Gap ACK blocks! So, more packets can
be enqueued and transmitted.
In addition, the sending side can now do "multi-retransmissions"
according to the Gaps reported in the Gap ACK blocks.
The new algorithm as verified helps greatly improve the TIPC throughput
especially under packet loss condition.
So far, a maximum of 32 blocks is quite enough without any "Too few Gap
ACK blocks" reports with a 5.0% packet loss rate, however this number
can be increased in the furture if needed.
Also, the patch is backward compatible.

I dropped the ball a bit here: these patches should all probably have
been part of rc2, but I wanted to get around to properly testing them in
the various configurations (qemu32, qeum64, unleashed) first.
Unfortunately I've been traveling and didn't have time to actually do
that, but since these fix concrete bugs and pass my old set of tests I
don't want to delay the fixes any longer.
There are four independent fixes here:
* A fix for the rv32 port that corrects the 64-bit user accesor's fixup
label address.
* A fix for a regression introduced during the merge window that broke
medlow configurations at run time. This patch also includes a fix
that disables ftrace for the same set of functions, which was found by
inspection at the same time.
* A modification of the memory map to avoid overlapping the FIXMAP and
VMALLOC regions on systems with small memory maps.
* A fix to the module handling code to use the correct syntax for
probing Kconfig entries.
These have passed my standard test flow, but I didn't have time to
expand that like I said I would.

that, but since these fix concrete bugs and pass my old set of tests I
don't want to delay the fixes any longer.
There are four independent fixes here:
- A fix for the rv32 port that corrects the 64-bit user accesor's
fixup label address.
- A fix for a regression introduced during the merge window that
broke medlow configurations at run time. This patch also includes a
fix that disables ftrace for the same set of functions, which was
found by inspection at the same time.
- A modification of the memory map to avoid overlapping the FIXMAP
and VMALLOC regions on systems with small memory maps.
- A fix to the module handling code to use the correct syntax for
probing Kconfig entries.
These have passed my standard test flow, but I didn't have time to
expand that testing like I said I would"

net: phy: use generic PHY ability readers if callback get_features isn't set
Meanwhile we have generic functions for reading the abilities of
Clause 22 / 45 PHY's. This allows to use them as fallback in case
callback get_features isn't set. Benefit is the reduction of
boilerplate code in PHY drivers.

mismatches.

Linux currently disable ECN for incoming connections when the SYN
requests ECN and the IP header has ECT(0)/ECT(1) set, as some
networks were reportedly mangling the ToS byte, hence could later
trigger false congestion notifications.
RFC8311 §4.3 relaxes RFC3168's requirements such that ECT can be set
one TCP control packets (including SYNs). The main benefit of this
is the decreased probability of losing a SYN in a congested
ECN-capable network (i.e., it avoids the initial 1s timeout).
Additionally, this allows the development of newer TCP extensions,
such as AccECN.
This patch relaxes the previous check, by enabling ECN on incoming
connections using SYN+ECT if at least one bit of the reserved flags
of the TCP header is set. Such bit would indicate that the sender of
the SYN is using a newer TCP feature than what the host implements,
such as AccECN, and is thus implementing RFC8311. This enables
end-hosts not supporting such extensions to still negociate ECN, and
to have some of the benefits of using ECN on control packets.

Currently if the driver registers devlink port instance, he should set
the devlink port attributes as well. Then the devlink core is able to
obtain switch id itself, no need for driver to implement the ndo.
Once all drivers will implement devlink port registration, this ndo
should be removed. This warning guides new drivers to do things as
they should be done.
