Very bad -- if your duplex has been negotiated correctly, frame errors
usually indicate bad cables.  Usually mis-paired cables.  (My favorite is
"they can't be mispaired, I made them myself".  The pairing only makes
sense if you think like phone guy.)

Looks pretty much OK to me.

Hmmm, there are no symbol errors reported in register 20..23.
I would expect symbol errors to result in non-zero counts.
