To integrate MRP into the bridge, the bridge needs to do the following:
- detect if the MRP frame was received on MRP ring port in that case it would be
processed otherwise just forward it as usual.
- enable parsing of MRP
- before whenever the bridge was set up, it would set all the ports in
forwarding state. Add an extra check to not set ports in forwarding state if
the port is an MRP ring port. The reason of this change is that if the MRP
instance initially sets the port in blocked state by setting the bridge up it
would overwrite this setting.

Implement the MRP API.
In case the HW can't generate MRP Test frames then the SW will try to generate
the frames. In case that also the SW will fail in generating the frames then a
error is return to the userspace. The userspace is responsible to generate all
the other MRP frames regardless if the test frames are generated by HW or SW.
The forwarding/termination of MRP frames is happening in the kernel and is done
by the MRP instance. The userspace application doesn't do the forwarding.

Extend switchdev API to add support for MRP. The HW is notified in

SWITCHDEV_OBJ_ID_MRP: This is used when a MRP instance is added/removed
from the MRP ring.
SWITCHDEV_OBJ_ID_RING_ROLE_MRP: This is used when the role of the node
changes. The current supported roles are MRM and MRC.
SWITCHDEV_OBJ_ID_RING_TEST_MRP: This is used when to start/stop sending
MRP_Test frames on the mrp ring ports. This is called only on nodes that have
the role MRM. In case this fails then the SW will generate the frames.
SWITCHDEV_OBJ_ID_RING_STATE_STATE: This is used when the ring changes it states
to open or closed. This is required to notify HW because the MRP_Test frame
contains the field MRP_InState which contains this information.
SWITCHDEV_ATTR_ID_MRP_PORT_STATE: This is used when the port's state is
changed. It can be in blocking/forwarding mode.
SWITCHDEV_ATTR_ID_MRP_PORT_ROLE: This is used when port's role changes. The
roles of the port can be primary/secondary. This is required to notify HW
because the MRP_Test frame contains the field MRP_PortRole that contains this
information.

Define the MRP interface.
This interface is used by the netlink to update the MRP instances and by the MRP
to make the calls to switchdev to offload it to HW.
It defines an MRP instance 'struct br_mrp' which is a list of MRP instances.
Which will be part of the 'struct net_bridge'. Each instance has 2 ring ports,
a bridge and an ID.
In case the HW can't generate MRP Test frames then the SW will generate those.
br_mrp_add - adds a new MRP instance.
br_mrp_del - deletes an existing MRP instance. Each instance has an ID(ring_id).
br_mrp_set_port_state - changes the port state. The port can be in forwarding
state, which means that the frames can pass through or in blocked state which
means that the frames can't pass through except MRP frames. This will
eventually call the switchdev API to notify the HW. This information is used
also by the SW bridge to know how to forward frames in case the HW doesn't
have this capability.
br_mrp_set_port_role - a port role can be primary or secondary. This
information is required to be pushed to HW in case the HW can generate
MRP_Test frames. Because the MRP_Test frames contains a file with this
information. Otherwise the HW will not be able to generate the frames
correctly.
br_mrp_set_ring_state - a ring can be in state open or closed. State open means
that the mrp port stopped receiving MRP_Test frames, while closed means that
the mrp port received MRP_Test frames. Similar with br_mrp_port_role, this
information is pushed in HW because the MRP_Test frames contain this
information.
br_mrp_set_ring_role - a ring can have the following roles MRM or MRC. For the
role MRM it is expected that the HW can terminate the MRP frames, notify the
SW that it stopped receiving MRP_Test frames and trapp all the other MRP
frames. While for MRC mode it is expected that the HW can forward the MRP
frames only between the MRP ports and copy MRP_Topology frames to CPU. In
case the HW doesn't support a role it needs to return an error code different
than -EOPNOTSUPP.
br_mrp_start_test - this starts/stops the generation of MRP_Test frames. To stop
the generation of frames the interval needs to have a value of 0. In this case
the userspace needs to know if the HW supports this or not. Not to have
duplicate frames(generated by HW and SW). Because if the HW supports this then
the SW will not generate anymore frames and will expect that the HW will
notify when it stopped receiving MRP frames using the function
br_mrp_port_open.
br_mrp_port_open - this function is used by drivers to notify the userspace via
a netlink callback that one of the ports stopped receiving MRP_Test frames.
This function is called only when the node has the role MRM. It is not
supposed to be called from userspace.
br_mrp_port_switchdev_add - this corresponds to the function br_mrp_add,
and will notify the HW that a MRP instance is added. The function gets
as parameter the MRP instance.
br_mrp_port_switchdev_del - this corresponds to the function br_mrp_del,
and will notify the HW that a MRP instance is removed. The function
gets as parameter the ID of the MRP instance that is removed.
br_mrp_port_switchdev_set_state - this corresponds to the function
br_mrp_set_port_state. It would notify the HW if it should block or not
non-MRP frames.
br_mrp_port_switchdev_set_port - this corresponds to the function
br_mrp_set_port_role. It would set the port role, primary or secondary.
br_mrp_switchdev_set_role - this corresponds to the function
br_mrp_set_ring_role and would set one of the role MRM or MRC.
br_mrp_switchdev_set_ring_state - this corresponds to the function
br_mrp_set_ring_state and would set the ring to be open or closed.
br_mrp_switchdev_send_ring_test - this corresponds to the function
br_mrp_start_test. This will notify the HW to start or stop generating
MRP_Test frames. Value 0 for the interval parameter means to stop generating
the frames.
br_mrp_port_open - this function is used to notify the userspace that the port
lost the continuity of MRP Test frames.

In MPTCP, the receive window is shared across all subflows, because it
refers to the mptcp-level sequence space.
MPTCP receivers already place incoming packets on the mptcp socket
receive queue and will charge it to the mptcp socket rcvbuf until
userspace consumes the data.
Update __tcp_select_window to use the occupancy of the parent/mptcp
socket instead of the subflow socket in case the tcp socket is part
of a logical mptcp connection.
This commit doesn't change choice of initial window for passive or active
connections.
While it would be possible to change those as well, this adds complexity
(especially when handling MP_JOIN requests). Furthermore, the MPTCP RFC
specifically says that a MPTCP sender 'MUST NOT use the RCV.WND field
of a TCP segment at the connection level if it does not also carry a DSS
option with a Data ACK field.'
SYN/SYNACK packets do not carry a DSS option with a Data ACK field.

Currently, the PF driver removes all (including its VFs') MAC/VLAN
flow director table entries when resetting, and restores them after

In fact, the hardware will clear all table entries only in IMP

entries in these cases, and needs do nothing when PF reset, FLR
or other function level reset.

Reorder include paths to ensure that runqslower sources are picking up
vmlinux.h, generated by runqslower's own Makefile. When runqslower is built
from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it
might pick up not-yet-complete vmlinux.h, generated by selftests Makefile,
which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT)
goes first and rely on runqslower's Makefile own dependency chain to ensure
vmlinux.h is properly completed before source code relying on it is compiled.
