Marvell PPv2 Header Parser sets some bits in the 'result_info' field in
each lookup iteration, to identify different packet attributes such as
DSA / VLAN tag, protocol infos, etc. This is used in further
classification stages in the controller.

is a single VLAN tag.

devlink: introduce port flavours and common phys_port_name generation
This patchset resolves 2 issues we have right now:
1) There are many netdevices / ports in the system, for port, pf, vf
represenatation but the user has no way to see which is which
2) The ndo_get_phys_port_name is implemented in each driver separatelly,
which may lead to inconsistent names between drivers.
This patchset introduces port flavours which should address the first
problem. In this initial patchset, I focus on DSA and their port
flavours. As a follow-up, I plan to add PF and VF representor flavours.
However, that needs additional dependencies in drivers (nfp, mlx5).
The common phys_port_name generation is used by mlxsw. An example output
for mlxsw looks like this:
...
pci/0000:03:00.0/59: type eth netdev enp3s0np4 flavour physical number 4
pci/0000:03:00.0/61: type eth netdev enp3s0np1 flavour physical number 1
pci/0000:03:00.0/63: type eth netdev enp3s0np2 flavour physical number 2
pci/0000:03:00.0/49: type eth netdev enp3s0np8s0 flavour physical number 8 split_group 8 subport 0
pci/0000:03:00.0/50: type eth netdev enp3s0np8s1 flavour physical number 8 split_group 8 subport 1
pci/0000:03:00.0/51: type eth netdev enp3s0np8s2 flavour physical number 8 split_group 8 subport 2
pci/0000:03:00.0/52: type eth netdev enp3s0np8s3 flavour physical number 8 split_group 8 subport 3
As you can see, the netdev names are generated according to the flavour
and port number. In case the port is split, the split subnumber is also
included.
An example output for dsa_loop testing module looks like this:
mdio_bus/fixed-0:1f/0: type eth netdev lan1 flavour physical number 0
mdio_bus/fixed-0:1f/1: type eth netdev lan2 flavour physical number 1
mdio_bus/fixed-0:1f/2: type eth netdev lan3 flavour physical number 2
mdio_bus/fixed-0:1f/3: type eth netdev lan4 flavour physical number 3
mdio_bus/fixed-0:1f/4: type notset
mdio_bus/fixed-0:1f/5: type notset flavour cpu number 5

This model allows to offload TC eswitch rules between VFs belonging

tcp: implement SACK compression
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.
Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.
This patch series adds SACK compression, but the infrastructure
could be leveraged to also compress ACK in the future.
v2: Addressed Neal feedback.
Added two sysctls to allow fine tuning, or even disabling the feature.

Wifi networks suffer from this aggressive behavior, but generally

This patch adds a high resolution timer and tp->compressed_ack counter.
Instead of sending a SACK, we program this timer with a small delay,
based on RTT and capped to 1 ms :
delay = min ( 5 % of RTT, 1 ms)
If subsequent SACKs need to be sent while the timer has not yet
expired, we simply increment tp->compressed_ack.
When timer expires, a SACK is sent with the latest information.
Whenever an ACK is sent (if data is sent, or if in-order
data is received) timer is canceled.
Note that tcp_sack_new_ofo_skb() is able to force a SACK to be sent
if the sack blocks need to be shuffled, even if the timer has not
expired.
A new SNMP counter is added in the following patch.

net: stmmac: Clean-up and tune-up
This targets to uniformize the handling of the different GMAC versions in
stmmac_main.c file and also tune-up the HW.
Currently there are some if/else conditions in the main source file which
calls different callbacks depending on the ID of GMAC.
With the introducion of a generic HW interface handling which automatically
selects the GMAC callbacks to be used, it is now unpleasant to see if
conditions in the main code because this should be completely agnostic of the
GMAC version.
This series removes most of these conditions. There are some if conditions
that remain untouched but the callbacks handling are now uniformized.
Tested in GMAC5, hope I didn't break any previous versions.

We either have .enable_dma_transmission or .set_tx_tail_ptr in the HW
table callbacks, we can never have both so there is no need to check for
GMAC version.

Instead of relying on the GMAC version for choosing if we need to use
dma_init or dma_init_{rx/tx}_chan callback, lets uniformize this and
always use the dma_init_{rx/tx}_chan callbacks.
While at it, fix the use of dma_init_chan callback, which shall be
called for as many channels as the max of rx/tx channels.

PTP and MMC modules base address can depend on the GMAC version. As this
is HW specific lets move this base address calculation to hwif.c. Also,
add an entry in the HW table so that we can specify the module offset.
This can later be extended to more modules, if deemed necessary.

With the introducion of callbacks check in hwif.h we only call the
callback if HW supports it so there is no longer need to check for GMAC
version.

Instead of relying on the GMAC version for choosing if we need to use
dma_{rx/tx}_mode or just dma_mode callback lets uniformize this and
always use the dma_{rx/tx}_mode callbacks.

Stop using if conditions depending on the GMAC version for clearing the
descriptor and use instead a helper implemented in the descriptor files.
