Hello, on an 4.9.x kernel using the freescale/fec driver "behind" a switch I had problems with packet reception.
Commit fbbeefdd2104 ("net: fec: Allow reception of frames bigger than 1522 bytes") fixed it for me and so I suggest to queue that one for stable. It can be cherry-picked to 4.9.x without conflict and IMHO should be applied to all stable branches before v4.14.
