This is unset for the ipq806x variant. Looking at older patches for this it seems the RX + TXs buffers can be up to 8k, so set appropriately. (I sent this as an RFC patch in June last year, but received no replies. I've been running with this on my hardware (a MikroTik RB3011) since then with larger MTUs to support both the internal qca8k switch and VLANs with no problems. Without the patch it's impossible to set the larger MTU required to support this.)
