This series adds link aggregation and VLAN filtering hardware offload

PTP is also on the list of features but it will probably not be

While removing queues from the XPS map, the individual CPU ID
alone was used to index the CPUs map, this should be changed to also
factor in the traffic class mapping for the CPU-to-queue lookup.
Fixes: 184c449f91fe ("net: Add support for XPS with QoS via traffic classes")

I was hoping that would be the case.

As explained in commit 9f9843a751d0 ("tcp: properly handle stretch
acks in slow start"), TCP stacks have to consider how many packets
are acknowledged in one single ACK, because of GRO, but also
because of ACK compression or losses.
We plan to add SACK compression in the following patch, we

Hi,
Again thanks for a thoughtful review. This will definitely will improve
the code.

When TCP receives an out-of-order packet, it immediately sends
a SACK packet, generating network load but also forcing the
receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.

This per netns sysctl allows for TCP SACK compression fine-tuning.

This per netns sysctl allows for TCP SACK compression fine-tuning.
This limits number of SACK that can be compressed.
Using 0 disables SACK compression.

This counter tracks number of ACK packets that the host has not sent,
thanks to ACK compression.
Sample output :

Currently sk_msg programs only have access to the raw data. However,
it is often useful when building policies to have the policies specific
to the socket endpoint. This allows using the socket tuple as input
into filters, etc.
This patch adds ctx access to the sock fields.

In this series we add the ability for sk msg programs to read basic
sock information about the sock they are attached to. The second
