Define a new helper to figure out the correct route scope to use on TX,
depending on socket configuration, ancillary data and send flags.
Use this new helper to properly initialise the scope in
flowi4_init_output(), instead of overriding tos with the RTO_ONLINK
flag.
The objective is to eventually remove RTO_ONLINK, which will allow
converting .flowi4_tos to dscp_t.

Add support for using IPv6 Big TCP on DQ which can handle large TSO/GRO
packets. See https://lwn.net/Articles/895398/. This can improve the
throughput and CPU usage.
Perf test result:
ip -d link show $DEV
gso_max_size 185000 gso_max_segs 65535 tso_max_size 262143 tso_max_segs 65535 gro_max_size 185000
For performance, tested with neper using 9k MTU on hardware that supports 200Gb/s line rate.
In single streams when line rate is not saturated, we expect throughput improvements.
When the networking is performing at line rate, we expect cpu usage improvements.

David Howells says:
====================
splice, net: Replace sendpage with sendmsg(MSG_SPLICE_PAGES), part 1
Here's the first tranche of patches towards providing a MSG_SPLICE_PAGES
internal sendmsg flag that is intended to replace the ->sendpage() op with
calls to sendmsg(). MSG_SPLICE_PAGES is a hint that tells the protocol
that it should splice the pages supplied if it can and copy them if not.
This will allow splice to pass multiple pages in a single call and allow
certain parts of higher protocols (e.g. sunrpc, iwarp) to pass an entire
message in one go rather than having to send them piecemeal. This should
also make it easier to handle the splicing of multipage folios.
A helper, skb_splice_from_iter() is provided to do the work of splicing or
copying data from an iterator. If a page is determined to be unspliceable
(such as being in the slab), then the helper will give an error.
Note that this facility is not made available to userspace and does not
provide any sort of callback.
This set consists of the following parts:
(1) Define the MSG_SPLICE_PAGES flag and prevent sys_sendmsg() from being
able to set it.
(2) Add an extra argument to skb_append_pagefrags() so that something
other than MAX_SKB_FRAGS can be used (sysctl_max_skb_frags for
example).
(3) Add the skb_splice_from_iter() helper to handle splicing pages into
skbuffs for MSG_SPLICE_PAGES that can be shared by TCP, IP/UDP and
AF_UNIX.
(4) Implement MSG_SPLICE_PAGES support in TCP.
(5) Make do_tcp_sendpages() just wrap sendmsg() and then fold it in to its
various callers.
(6) Implement MSG_SPLICE_PAGES support in IP and make udp_sendpage() just
a wrapper around sendmsg().
(7) Implement MSG_SPLICE_PAGES support in IP6/UDP6.
(8) Implement MSG_SPLICE_PAGES support in AF_UNIX.
(9) Make AF_UNIX copy unspliceable pages.

network protocol that it should splice pages from the source iterator
rather than copying the data if it can. This flag is added to a list that

This is intended as a replacement for the ->sendpage() op, allowing a way
to splice in several multipage folios in one go.

Add layer 4 RSS hashing on UDP traffic to allow for the
utilization of multiple queues for multiple connections on
the same IP address.
Previously, since the introduction of the driver, RSS hashing
was only performed on the source and destination IP addresses
of UDP packets thereby limiting UDP traffic to a single queue
for multiple connections on the same IP address. The transport
layer is now included in RSS hashing for UDP traffic, which
was not previously the case. The reason behind the previous
limitation is unclear - either a historic limitation of the
NFP device, or an oversight.

drivers fill in the supported_interfaces bitmap, it is time to enforce
this. We have already required supported_interfaces to be set in order
for optical SFPs to be configured in commit f81fa96d8a6c ("net: phylink:

Refuse phylink creation if supported_interfaces is empty, and remove

number of WT_502. Fiberstore use v2.2 whereas Walsun use v2.6.
These modules contain a Marvell AQrate AQR113C PHY, accessible through
I2C 0x51 using the "rollball" protocol. In both cases, the PHY is
programmed to use 10GBASE-R with pause-mode rate adaption.
Unlike the other rollball modules, these only need a four second delay
before we can talk to the PHY.

ice: allow matching on meta data
Michal Swiatkowski says:
This patchset is intended to improve the usability of the switchdev
slow path. Without matching on a meta data values slow path works
based on VF's MAC addresses. It causes a problem when the VF wants
to use more than one MAC address (e.g. when it is in trusted mode).
Parse all meta data in the same place where protocol type fields are
parsed. Add description for the currently implemented meta data. It is
important to note that depending on DDP not all described meta data can
be available. Using not available meta data leads to error returned by
function which is looking for correct words in profiles read from DDP.
There is also one small improvement, remove of rx field in rule info
structure (patch 2). It is redundant.

If log_max_l2_table is 0 there is no really room for one L2 address.
and should be treated as not supported.
Do the check in MPFS init and for vport context events which
both used to update L2 address.

Checking sriov is done on the pci device so it can return true
on other devices like SF but nothing should be done in this case.
Add a check that the device is PF.

The use of a source MAC to direct packets from the VF to the corresponding
port representor is only ok if there is only one MAC on a VF. To support
this functionality when the number of MACs on a VF is greater, it is
necessary to match a source VSI instead of a source MAC.
Let's use the new switch API that allows matching on metadata.
If MAC isn't used in match criteria there is no need to handle adding
rule after virtchnl command. Instead add new rule while port representor
is being configured.
Remove rule_added field, checking for sp_rule can be used instead.
Remove also checking for switchdev running in deleting rule as it can be
called from unroll context when running flag isn't set. Checking for
sp_rule covers both context (with and without running flag).
Rules are added in eswitch configuration flow, so there is no need to
have replay function.
