Here is what Vladimir says about it:
at803x_aneg_done() keeps the aneg reporting as "not done" even when
the copper-side link was reported as up, but the in-band autoneg has
not finished.
That was the _intended_ behavior when that code was introduced, and
Heiner have said about it [1]:
| That's not nice from the PHY:
| It signals "link up", and if the system asks the PHY for link details,
| then it sheepishly says "well, link is *almost* up".
If the specification of phy_aneg_done behavior does not include
in-band autoneg (and it doesn't), then this piece of code does not
belong here.
The fact that we can no longer trigger this code from phylib is yet
another reason why it fails at its intended (and wrong) purpose and
should be removed.
Removing the SGMII link check, would just keep the call to
genphy_aneg_done(), which is also the fallback. Thus we can just remove
at803x_aneg_done() altogether.

When using short intervals e.g. below one millisecond, large packets won't be
transmitted at all. The software implementations checks whether the packet can
be fit into the remaining interval. Therefore, it takes the packet length and
the transmission speed into account. That is correct.
However, for large packets it may be that the transmission time exceeds the
interval resulting in no packet transmission. The same situation works fine with
hardware offloading applied.
The problem has been observed with the following schedule and iperf3:
|tc qdisc replace dev lan1 parent root handle 100 taprio \
| num_tc 8 \
| map 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 \

After debugging, it seems that the packet length stored in the SKB is about
7000-8000 bytes. Using a 100 Mbit/s link the transmission time is about 600us
which larger than the interval of 500us.
Therefore, segment the SKB into smaller chunks if the packet is too big. This
yields similar results than the hardware offload:
|root@tsn:~# iperf3 -c 192.168.2.105
|Connecting to host 192.168.2.105, port 5201

Furthermore, the segmentation can be skipped for the full offload case, as the
driver or the hardware is expected to handle this.

net: avoid retpoline overhead on VLAN and TEB GRO
dev_gro_receive() uses indirect calls for IP GRO functions, but
it works only for the outermost headers and untagged frames.
Simple VLAN tag before an IP header restores the performance hit.
This simple series straightens the GRO calls for IP headers going
after VLAN tag or inner Ethernet header (GENEVE, NvGRE, VxLAN)

The ocelot switches are a bit odd in that they do not have an STP state
to put the ports into. Instead, the forwarding configuration is delayed
from the typical port_bridge_join into stp_state_set, when the port enters
the BR_STATE_FORWARDING state.
I can only guess that the implementation of this quirk is the reason that
led to the simplification of the driver such that only one bridge could
be offloaded at a time.
We can simplify the data structures somewhat, and introduce a per-port
bridge device pointer and STP state, similar to how the LAG offload
works now (there we have a per-port bonding device pointer and TX
enabled state). This allows offloading multiple bridges with relative
ease, while still keeping in place the quirk to delay the programming of
the PGIDs.
We actually need this change now because we need to remove the bogus
restriction from ocelot_bridge_stp_state_set that ocelot->bridge_mask
needs to contain BIT(port), otherwise that function is a no-op.

be a NULL port.

net: dsa: mv88e6xxx: Offload bridge port flags
Add support for offloading learning and broadcast flooding flags. With

Broadcast flooding is somewhat awkward to control as there is no
per-port bit for this like there is for unknown unicast and unknown
multicast. Instead we have to update the ATU entry for the broadcast
address for all currently used FIDs.

- Only return a netdev from dsa_port_to_bridge_port if the port is
currently bridged (Vladimir & Florian)
v1 -> v2:
- Ensure that mv88e6xxx_vtu_get handles VID 0 (Vladimir)
- Fixed off-by-one in mv88e6xxx_port_set_assoc_vector (Vladimir)

These switches have two modes of classifying broadcast:
1. Broadcast is multicast.
2. Broadcast is its own unique thing that is always flooded
everywhere.
This driver uses the first option, making sure to load the broadcast
address into all active databases. Because of this, we can support
per-port broadcast flooding by (1) making sure to only set the subset
of ports that have it enabled whenever joining a new bridge or VLAN,
and (2) by updating all active databases whenever the setting is
changed on a port.

Previously a standalone port would initially not egress any unknown

This does not matter that much since we only ever send FROM_CPUs on
standalone ports, but it seems prudent to make sure that the initial
values match those that are applied after a bridging/unbridging cycle.

In order for a driver to be able to query a bridge for information
about itself, e.g. reading out port flags, it has to use a netdev that
is known to the bridge. In the simple case, that is just the netdev
representing the port, e.g. swp0 or swp1 in this example:
br0
/ \
swp0 swp1
But in the case of an offloaded lag, this will be the bond or team
interface, e.g. bond0 in this example:
br0

bond0

swp0 swp1

use these operations on u32 and size_t objects. In a 32-bit kernel
build, size_t will be 32 bits wide, so there remains no reason to
use do_div() for divide and modulo.

net: xps: improve the xps maps handling
This series aims at fixing various issues with the xps code, including

The main change is moving dev->num_tc and dev->nr_ids in the xps maps, to
avoid out-of-bound accesses as those two fields can be updated after the
maps have been allocated. This allows further reworks, to improve the
xps code readability and allow to stop taking the rtnl lock when
reading the maps in sysfs. The maps are moved to an array in net_device,
which simplifies the code a lot.
One future improvement may be to remove the use of xps_map_mutex from
