This series starts with 2 patches to support firmware crash dump.  The
driver allocates the required DMA memory ahead of time for firmware to
store the crash dump if and when it crashes.  Patch 3 adds priority and
TPID for the .ndo_set_vf_vlan() callback.  Note that this was rejected
and reverted last year and it is being re-submitted after recent changes
in the guidelines.  The remaining patches are MSIX related.  Legacy
interrupt is no longer supported by firmware so we remove the support
in the driver.  We then convert to use the newer kernel APIs to
allocate and enable MSIX vectors.  The last patch adds support for
dynamic MSIX.

v4:
Simplify patch #9 based on feedback from Michal Swiatkowski.

Link to v3:
https://lore.kernel.org/netdev/20240823195657.31588-1-michael.chan@broadcom.com/

v3:
Some changes to patch #1, #2, and #8 based on feedback from Przemek
Kitszel and internal review.  I'm keeping Simon's Reviewed-by tags since
the changes are small.

Link to v2:
https://lore.kernel.org/netdev/20240816212832.185379-1-michael.chan@broadcom.com/

v2:
Only patch #4 is updated to fix a memory leakage reported by Simon.
The changelog of some of the MSIX patches have been updated based on
feedback from Bjorn Helgaas.

Some disturbance in the force on kernel.org, their bot isn't responding.
Applied a few hours ago, thanks!
