Here are the sha-sums, the 002 version changes to 003.
If someone could update openwrt to use them I'd appreciate it.  Changelog
is at the bottom.  I am hoping this resolves the crashes related to

   *  Jan 2, 2019:  Rebase patches to make 9980 bisectable.

   *  Jan 2, 2019:  Fix scheduling related assert when wal-peer is deleted with pending
      tx buffers (bug 54, and others)

   *  Jan 7, 2019:  Fix specifying retransmits for AMPDU frames.  It was previously ignored
      since it is a 'software' retransmit instead of a hardware retransmit.

   *  Jan 9 2019:  Fix potential way to get zero rates selected (and then assert)

   *  Jan 18 2019:  pfsched has specific work-around to just return if we find invalid flags AND
                    if we are in an out-of-order situation.  Maybe this is last of the pfsched
                    related issues (bug 54 and similar).

   *  Jan 24 2019:  The rcSibUpdate method can be called concurrently with IRQ tx-completion callback,
                    and that could potentially allow the tx-completion callback to see invalid state
                    and assert or otherwise mess up the rate-ctrl logic.  So, disable IRQs in
                    rcSibUpdate to prevent this.  Related to bug 58.

   *  Jan 28 2019:  Ensure that cached config is applied to ratectrl objects when fetched from
                    the cache.  This should fix part of bug 58.

   *  Jan 28 2019:  Ensure that ratectrl objects from cachemgr are always initialized.  This fixes
                    another part of bug 58.

   *  Jan 30 2019:  Better use of temporary rate-ctrl object.  Make sure it is initialized, simplify
                    code path.  This finishes up porting forward similar changes I made for wave-1
                    firmware long ago, and fixes another potential way to hit bug-58 issues.

   *  Jan 30 2019:  Cachemgr did not have a callback for when memory was logically freed.  This means
                    that peers could keep stale references to rate-ctrl objects that were in process
                    of being DMA'd into to load a different peer's rate-ctrl state.  This was causing
                    the bugcheck logic to fail early and often, and I suspect it might be a root cause
                    of bug 58 as well.  The fix is to add a callback and set any 'deleted' memory references
                    to NULL so that we cannot access it accidentally.  Thanks to excellent logs and patience
                    from the bug-58 reporter!
