Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.

With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.

The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.

Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.

The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.

This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.

The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

====================
Unmask upper DSCP bits - part 1

tl;dr - This patchset starts to unmask the upper DSCP bits in the IPv4
flow key in preparation for allowing IPv4 FIB rules to match on DSCP.
No functional changes are expected.

The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB
lookup to match against the TOS selector in FIB rules and routes.

It is currently impossible for user space to configure FIB rules that
match on the DSCP value as the upper DSCP bits are either masked in the
various call sites that initialize the IPv4 flow key or along the path
to the FIB core.

In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we
need to make sure the entire DSCP value is present in the IPv4 flow key.
This patchset starts to unmask the upper DSCP bits in the various places
that invoke the core FIB lookup functions directly (patches #1-#7) and
in the input route path (patches #8-#12). Future patchsets will do the
same in the output route path.

No functional changes are expected as commit 1fa3314c ("ipv4:
Centralize TOS matching") moved the masking of the upper DSCP bits to
the core where 'flowi4_tos' is matched against the TOS selector.

As explained in commit 35ebf65e ("ipv4: Create and use
fib_compute_spec_dst() helper."), the function is used - for example -
to determine the source address for an ICMP reply. If we are responding
to a multicast or broadcast packet, the source address is set to the
source address that we would use if we were to send a packet to the
unicast source of the original packet. This address is determined by
performing a FIB lookup and using the preferred source address of the
resulting route.

the reply so that in the future the FIB lookup could be performed

tc is always in the range 0 - cfg->tcs. And as cfg->tcs is a u8,
the range is 0 - 255. Further, on inspecting the code, it seems
that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so
the range is actually 0 - 8.

So, it seems that the condition that GCC flags will not occur.
But, nonetheless, it would be nice if it didn't emit the warning.

It seems that this can be achieved by changing the format specifier
from %d to %u, in which case I believe GCC recognises an upper bound
on the range of tc of 0 - 255. After some experimentation I think
this is due to the combination of the use of %u and the type of
cfg->tcs (u8).

Empirically, updating the type of the tc variable to unsigned int
has the same effect.

As both of these changes seem to make sense in relation to what the code
is actually doing - iterating over unsigned values - do both.

Compile tested only.

This typo in scripts/Makefile.build has been present for more than 20
years. It was accidentally copy-pasted to other scripts/Makefile.* files.

MAINTAINERS: Networking updates

This series includes Networking-related updates to MAINTAINERS.

* Patches 1-4 aim to assign header files with "*net*' and '*skbuff*'
  in their name to Networking-related sections within Maintainers.

  There are a few such files left over after this patches.
  I have to sent separate patches to add them to SCSI SUBSYSTEM
  and NETWORKING DRIVERS (WIRELESS) sections [1][2].

* Patch 5 updates the status of the JME driver to 'Odd Fixes'

This driver only appears to have received sporadic clean-ups, typically
part of some tree-wide activity, and fixes for quite some time.  And
according to the maintainer, Guo-Fu Tseng, the device has been EOLed for
a long time (see Link).

Accordingly, it seems appropriate to mark this driver as odd fixes.

This is part of an effort to assign a section in MAINTAINERS to header
files that relate to Networking. In this case the files with "net" or
"skbuff" in their name.

This patch adds a number of such files to the NETWORKING DRIVERS
and NETWORKING [GENERAL] sections.

This aims to add limited globs to improve the coverage of header files
in the NETWORKING DRIVERS and NETWORKING [GENERAL] sections.

It is done so in a minimal way to exclude overlap with other sections.
And so as not to require "X" entries to exclude files otherwise
matched by these new globs.

While imperfect, due to it's limited nature, this does extend coverage
of header files by these sections. And aims to automatically cover
new files that seem very likely belong to these sections.

The include/linux/netdev* glob (both sections)
+ Subsumes the entries for:
  - include/linux/netdevice.h
+ Extends the sections to cover
  - include/linux/netdevice_xmit.h
  - include/linux/netdev_features.h

The include/uapi/linux/netdev* globs: (both sections)
+ Subsumes the entries for:
  - include/linux/netdevice.h
+ Extends the sections to cover
  - include/linux/netdev.h

The include/linux/skbuff* glob (NETWORKING [GENERAL] section only):
+ Subsumes the entry for:
  - include/linux/skbuff.h
+ Extends the section to cover
  - include/linux/skbuff_ref.h

A include/uapi/linux/net_* glob was not added to the NETWORKING [GENERAL]
section. Although it would subsume the entry for
include/uapi/linux/net_namespace.h, which is fine, it would also extend
coverage to:
- include/uapi/linux/net_dropmon.h, which belongs to the
   NETWORK DROP MONITOR section
- include/uapi/linux/net_tstamp.h which, as per an earlier patch in this
  series, belongs to the SOCKET TIMESTAMPING section

It seems that sonet.h is included in ATM related source files,
and thus that ATM is the most relevant section for these files.

Some CPT AF registers are per LF and others are global. Translation
of PF/VF local LF slot number to actual LF slot number is required
only for accessing perf LF registers. CPT AF global registers access
do not require any LF slot number. Also, there is no reason CPT
PF/VF to know actual lf's register offset.

Without this fix microcode loading will fail, VFs cannot be created
and hardware is not usable.

The current implementation incorrectly sets the mode bit of the PHY chip.
Bit 15 (RTL8211F_LEDCR_MODE) should not be shifted together with the
configuration nibble of a LED- it should be set independently of the
index of the LED being configured.
As a consequence, the RTL8211F LED control is actually operating in Mode A.
Fix the error by or-ing final register value to write with a const-value of
RTL8211F_LEDCR_MODE, thus setting Mode bit explicitly.

A few tests check if nettest exists in the $PATH before adding
$PWD to $PATH and re-checking. They don't discard stderr on
the first check (and nettest is built as part of selftests,
so it's pretty normal for it to not be available in system $PATH).
This leads to output noise:

  which: no nettest in (/home/virtme/tools/fs/bin:/home/virtme/tools/fs/sbin:/home/virtme/tools/fs/usr/bin:/home/virtme/tools/fs/usr/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)

Add a common helper for the check which does silence stderr.

There is another small functional change hiding here, because pmtu.sh
and fib_rule_tests.sh used to return from the test case rather than
completely exit. Building nettest is not hard, there should be no need
to maintain the ability to selectively skip cases in its absence.
