      ====================
      Fixes for SJA1105 DSA: FDBs, Learning and PTP
      
      This is an assortment of functional fixes for the sja1105 switch driver
      targeted for the "net" tree (although they apply on net-next just as
      well).
      
      Patch 1/5 ("net: dsa: sja1105: Fix broken learning with vlan_filtering
      disabled") repairs a breakage introduced in the early development stages
      of the driver: support for traffic from the CPU has broken "normal"
      frame forwarding (based on DMAC) - there is connectivity through the
      switch only because all frames are flooded.
      I debated whether this patch qualifies as a fix, since it puts the
      switch into a mode it has never operated in before (aka SVL). But
      "normal" forwarding did use to work before the "Traffic support for
      SJA1105 DSA driver" patchset, and arguably this patch should have been
      part of that.
      Also, it would be strange for this feature to be broken in the 5.2 LTS.
      
      Patch 2/5 ("net: dsa: sja1105: Use the LOCKEDS bit for SJA1105 E/T as
      well") is a simplification of a previous FDB-related patch that is
      currently in the 5.3 rc's.
      
      Patches 3/5 - 5/5 fix various crashes found while running linuxptp over the
      switch ports for extended periods of time, or in conjunction with other
      error conditions. The fixed-up commits were all introduced in 5.2.

      net: dsa: sja1105: Fix memory leak on meta state machine error path · 93fa8587
      Vladimir Oltean authored
      When RX timestamping is enabled and two link-local (non-meta) frames are
      received in a row, this constitutes an error.
      
      The tagger is always caching the last link-local frame, in an attempt to
      merge it with the meta follow-up frame when that arrives. To recover
      from the above error condition, the initial cached link-local frame is
      dropped and the second frame in a row is cached (in expectance of the
      second meta frame).
      
      However, when dropping the initial link-local frame, its backing memory
      was being leaked.

      After a meta frame is received, it is associated with the cached
      sp->data->stampable_skb from the DSA tagger private structure.
      
      Cached means its refcount is incremented with skb_get() in order for
      dsa_switch_rcv() to not free it when the tagger .rcv returns NULL.
      
      The mistake is that skb_unref() is not the correct function to use. It
      will correctly decrement the refcount (which will go back to zero) but
      the skb memory will not be freed.  That is the job of kfree_skb(), which
      also calls skb_unref().
      
      But it turns out that freeing the cached stampable_skb is in fact not
      necessary.  It is still a perfectly valid skb, and now it is even
      annotated with the partial RX timestamp.  So remove the skb_copy()
      altogether and simply pass the stampable_skb with a refcount of 1
      (incremented by us, decremented by dsa_switch_rcv) up the stack.
