When removing multicast address in B0 steering mode there is
a bug in cases where there is a single QP registered for the address,
and this QP is also promiscuous. In such cases the entry wouldn't be
deleted from the SW structure representing all Ethernet MCG entries,
but would be removed in HW. This way when driver goes to remove it
from SW and HW structures the HW deletion fails.
Moreover the same index could later be used for registering
different address, which can be Infiniband.

When we run broadcast packets over dual bearers/interfaces, the
current transmission code is flipping bearers between each sent
packet, with the purpose of leveraging the double bandwidth
available. The receiving bclink is resequencing the packets if
needed, so all messages are delivered upwards from the broadcast
link in the correct order, even if they may arrive in concurrent
interrupts.
However, at the moment of delivery upwards to the socket, we release
all spinlocks (bclink_lock, node_lock), so it is still possible
that arriving messages bypass each other before they reach the socket
queue.
We fix this by applying the same technique we are using for unicast
traffic. We use a link selector (i.e., the last bit of sending port
number) to ensure that messages from the same sender socket always are
sent over the same bearer. This guarantees sequential delivery between
socket pairs, which is sufficient to satisfy the protocol spec, as well
as all known user requirements.

In this commit, we convert the socket multicast send function to
directly call the new multicast/broadcast function (tipc_bclink_xmit2())
introduced in the previous commit. We do this instead of letting the
call go via the now obsolete tipc_port_mcast_xmit(), hence saving
a call level and some code complexity.
We also remove the initial destination lookup at the message sending
side, and replace that with an unconditional lookup at the receiving
side, including on the sending node itself. This makes the destination
lookup and message transfer more uniform than before.

We add a new broadcast link transmit function in bclink.c and a new
receive function in socket.c. The purpose is to move the branching
between external and internal destination down to the link layer,
just as we have done with unicast in earlier commits. We also make
use of the new link-independent fragmentation support that was
introduced in an earlier commit series.
This gives a shorter and simpler code path, and makes it possible
to obtain copy-free buffer delivery to all node local destination
sockets.
The new transmission code is added in parallel with the existing one,
and will be used by the socket multicast send function in the next
commit in this series.

This patch adds the interrupt handling module, in kfd_interrupt.c, and its
related members in different data structures to the amdkfd driver.
The amdkfd interrupt module maintains an internal interrupt ring per amdkfd
device. The internal interrupt ring contains interrupts that needs further
handling. The extra handling is deferred to a later time through a workqueue.
There's no acknowledgment for the interrupts we use. The hardware simply queues
a new interrupt each time without waiting.
The fixed-size internal queue means that it's possible for us to lose
interrupts because we have no back-pressure to the hardware.
