Add xdp_txq_info as the Tx counterpart to xdp_rxq_info. At the
moment only the device is added. Other fields (queue_index)
can be added as use cases arise.
>From a UAPI perspective, add egress_ifindex to xdp context for
bpf programs to see the Tx device.
Update the verifier to only allow accesses to egress_ifindex by
XDP programs with BPF_XDP_DEVMAP expected attach type.

A node that has the MRA role, it can behave as MRM or MRC.
Initially it starts as MRM and sends MRP_Test frames on both ring ports.
If it detects that there are MRP_Test send by another MRM, then it
checks if these frames have a lower priority than itself. In this case
it would send MRP_Nack frames to notify the other node that it needs to
stop sending MRP_Test frames.
If it receives a MRP_Nack frame then it stops sending MRP_Test frames
and starts to behave as a MRC but it would continue to monitor the
MRP_Test frames send by MRM. If at a point the MRM stops to send
MRP_Test frames it would get the MRM role and start to send MRP_Test
frames.

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next
to extend ctnetlink and the flowtable infrastructure:
1) Extend ctnetlink kernel side netlink dump filtering capabilities,
from Romain Bellan.
2) Generalise the flowtable hook parser to take a hook list.
3) Pass a hook list to the flowtable hook registration/unregistration.
4) Add a helper function to release the flowtable hook list.
5) Update the flowtable event notifier to pass a flowtable hook list.
6) Allow users to add new devices to an existing flowtables.
7) Allow users to remove devices to an existing flowtables.
8) Allow for registering a flowtable with no initial devices.

Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface.
The tunnel device and route control plane does not provide an obvious
way to relate tunnel and physical devices.
This patch allows drivers to register a tunnel device offload handler
for the tc and netfilter frontends through flow_indr_dev_register() and
flow_indr_dev_unregister().
The frontend calls flow_indr_dev_setup_offload() that iterates over the
list of drivers that are offering tunnel device hardware offload
support and it sets up the flow block for this tunnel device.
If the driver module is removed, the indirect flow_block ends up with a
stale callback reference. The module removal path triggers the
dev_shutdown() path to remove the qdisc and the flow_blocks for the
physical devices. However, this is not useful for tunnel devices, where
relation between the physical and the tunnel device is not explicit.
This patch introduces a cleanup callback that is invoked when the driver
module is removed to clean up the tunnel device flow_block. This patch
defines struct flow_block_indr and it uses it from flow_block_cb to
store the information that front-end requires to perform the
flow_block_cb cleanup on module removal.

xdp_umem.c had overlapping changes between the 64-bit math fix
for the calculation of npgs and the removal of the zerocopy
memory type which got rid of the chunk_size_nohdr member.
The mlx5 Kconfig conflict is a case where we just take the
net-next copy of the Kconfig entry dependency as it takes on
the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

These capabilities cover what would otherwise be transported
in HT/VHT capabilities, but only a subset thereof that is
actually needed on 6 GHz with HE already present. Expose the
capabilities to userspace, drivers are expected to set them
as using the 6 GHz band (currently) requires HE capability.

Make tcp_ld_RTO_revert() helper available to IPv6, and

Quoting this RFC :
3. Connectivity Disruption Indication
For Internet Protocol version 6 (IPv6) [RFC2460], the counterpart of
the ICMP destination unreachable message of code 0 (net unreachable)
and of code 1 (host unreachable) is the ICMPv6 destination
unreachable message of code 0 (no route to destination) [RFC4443].
As with IPv4, a router should generate an ICMPv6 destination
unreachable message of code 0 in response to a packet that cannot be
delivered to its destination address because it lacks a matching
entry in its routing table.
