When going into a firmware upgrade cycle, we set the device as

The version 1 Tx queues can use longer SG lists than the
original version 0 queues, but we need to check to see if the
firmware supports the v1 Tx queues. This implements the queue
type query for all queue types, and uses the information to
set up for using the longer Tx SG lists.
Because the Tx SG list can be longer, we need to limit the
max ring length to be sure we stay inside the boundaries of a
DMA allocation max size, so we lower the max Tx ring size.
The driver sets its highest known version in the Q_IDENTITY
command, and the FW returns the highest version that it knows,
bounded by the driver's version. The negotiated version number
is later used in the Q_INIT commands.

When running in a bond setup, or some other potential

the default device mac. Since the userland doesn't know
about the changes going on under the covers in a fw-upgrade

needs to leave the netdev mac filter alone when rebuilding
after the fw-upgrade.

When the other MPTCP-peer uses 32-bit data-sequence numbers, we rely on
map_seq to indicate how to expand to a 64-bit data-sequence number in
expand_seq() when receiving data.
For new subflows, this field is not initialized, thus results in an
"invalid" mapping being discarded.
Fix this by initializing map_seq upon subflow establishment time.

Building a kernel with clang sometimes fails with an objtool error in dlm:
fs/dlm/lock.o: warning: objtool: revert_lock_pc()+0xbd: can't find jump dest instruction at .text+0xd7fc
The problem is that BUG() never returns and the compiler knows
that anything after it is unreachable, however the panic still
emits some code that does not get fully eliminated.
Having both BUG() and panic() is really pointless as the BUG()
kills the current process and the subsequent panic() never hits.
In most cases, we probably don't really want either and should
replace the DLM_ASSERT() statements with WARN_ON(), as has
been done for some of them.
Remove the BUG() here so the user at least sees the panic message
and we can reliably build randconfig kernels.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

- The preempt_irq_delay_thread fix to make the creation code
wait for the kthread to finish to prevent it from executing after
module unload, can now cause the kthread to exit before it even
executes (preventing it to run its tests).
- The fix to the bootconfig that fixed the initrd to remove the
