====================
MPTCP: Cleanup and address advertisement fixes
This patch series contains cleanup and fixes we have been testing in the
MPTCP tree. MPTCP uses TCP option headers to advertise additional
address information after an initial connection is established. The main
fixes here deal with making those advertisements more reliable and
improving the way subflows are created after an advertisement is
received.
Patches 1, 2, 4, 10, and 12 are for various cleanup or refactoring.
Patch 3 skips an extra connection attempt if there's already a subflow
connection for the newly received advertisement.
Patches 5, 6, and 7 make sure that the next address is advertised when
there are multiple addresses to share, the advertisement has been
retried, and the peer has not echoed the advertisement. Self tests are
updated.
Patches 8 and 9 fix a problem similar to 5/6/7, but covers a case where
the failure was due to a subflow connection not completing.
Patches 11 and 13 send a bare ack to revoke an advertisement rather than
waiting for other activity to trigger a packet send. This mirrors the
way acks are sent for new advertisements. Self test is included.

Merge branch 'ipa-resource'
Alex Elder says:
====================
net: ipa: rework resource programming
This series reworks the way IPA resources are defined and
programmed. It is a little long--and I apologize for that--but
I think the patches are best taken together as a single unit.
The IPA hardware operates with a set of distinct "resources." Each
hardware instance has a fixed number of each resource type available.
Available resources are divided into smaller pools, with each pool
shared by endpoints in a "resource group." Each endpoint is thus
assigned to a resource group that determines which pools supply
resources the IPA hardware uses to handle the endpoint's processing.
The exact set of resources used can differ for each version of IPA.
Except for IPA v3.0 and v3.1, there are 5 source and 2 destination
resource types, but there's no reason to assume this won't change.
The number of resource groups used *does* typically change based on
the hardware version. For example, some versions target reduced
functionality and support fewer resource groups.
With that as background...
The net result of this series is to improve the flexibility with
which IPA resources and resource groups are defined, permitting each
version of IPA to define its own set of resources and groups. Along
the way it isolates the resource-related code, and fixes a few bugs
related to resource handling.
The first patch moves resource-related code to a new C file (and
header). It generates a checkpatch warning about updating
MAINTAINERS, which can be ignored. The second patch fixes a bug,
but the bug does not affect SDM845 or SC7180.
The third patch defines an enumerated type whose members provide
symbolic names for resource groups.
The fourth defines some resource limits for SDM845 that were not
previously being programmed. That platform "works" without this,
but to be correct, these limits should really be programmed.
The fifth patch uses a single enumerated type to define both source
and destination resource type IDs, and the sixth uses those IDs to
index the resource limit arrays. The seventh moves the definition
of that enumerated type into the platform data files, allowing each
platform to define its own set of resource types.
The eighth and ninth are fairly trivial changes. One replaces two
"max" symbols having the same value with a single symbol. And the
other replaces two distinct but otherwise identical structure types
with a single common one.
The 10th is a small preparatory patch for the 11th, passing a
different argument to a function that programs resource values.
The 11th allows the actual number of source and destination resource
groups for a platform to be specified in its configuration data.
That way the number is based on the actual number of groups defined.
This removes the need for a sort of clunky pair of functions that
defined that information previously.
Finally, the last patch just increases the number of resource groups
that can be defined to 8.

Add a new field to the resource configuration data that indicates

net: stmmac: enable multi-vector MSI
This patchset adds support for multi MSI interrupts in addition to
current single common interrupt implementation. Each MSI interrupt is tied
to a newly introduce interrupt service routine(ISR). Hence, each interrupt
will only go through the corresponding ISR.
In order to increase the efficiency, enabling multi MSI interrupt will
automatically select the interrupt mode configuration INTM=1. When INTM=1,
the TX/RX transfer complete signal will only asserted on corresponding
sbd_perch_tx_intr_o[] or sbd_perch_rx_intr_o[] without asserting signal
on the common sbd_intr_o. Hence, for each TX/RX interrupts, only the
corresponding ISR will be triggered.

Merge branch 'ethtool-FEC'
Jakub Kicinski says:
====================
ethtool: clarify the ethtool FEC interface
Our FEC configuration interface is one of the more confusing.
It also lacks any error checking in the core. This certainly
shows in the varying implementations across the drivers.
Improve the documentation and add most basic checks. Sadly, it's
probably too late now to try to enforce much more uniformity.
Any thoughts & suggestions welcome. Next step is to add netlink
for FEC, then stats.

ethtool: clarify the ethtool FEC interface
The definition of the FEC driver interface is quite unclear.
Improve the documentation.
This is based on current driver and user space code, as well
as the discussions about the interface:

ethtool: fec: sanitize ethtool_fecparam->fec
Reject NONE on set, this mode means device does not support
FEC so it's a little out of place in the set interface.
This should be safe to do - user space ethtool does not allow
the use of NONE on set. A few drivers treat it the same as OFF,
but none use it instead of OFF.
Similarly reject an empty FEC mask. The common user space tool
will not send such requests and most drivers correctly reject
it already.

ethtool: fec: sanitize ethtool_fecparam->active_fec
struct ethtool_fecparam::active_fec is a GET-only field,
all in-tree drivers correctly ignore it on SET. Clear
the field on SET to avoid any confusion. Again, we can't
reject non-zero now since ethtool user space does not
zero-init the param correctly.

ethtool: fec: sanitize ethtool_fecparam->reserved
struct ethtool_fecparam::reserved is never looked at by the core.
Make sure it's actually 0. Unfortunately we can't return an error
because old ethtool doesn't zero-initialize the structure for SET.
On GET we can be more verbose, there are no in tree (ab)users.
Fix up the kdoc on the structure. Remove the mention of FEC
bypass. Seems like a niche thing to configure in the first
place.
