As modifying sky2 code I have not could get any solution, then I have
modified some parameters on the ethernet interface and using a MTU =
1503 and disabling TSO (TCP Segmentation Offload) mechanism all
communication errors disappear, both the rx errors due to too long
packets and tx timeout er
Also, check that in sky2_rx_add(), le->length is set to 4K.
The value of le->length is set to 1520.

Ah.
You probably need to change sky2_get_rx_data_size() as well, to add in
the extra 8 bytes.

If I add the extra 8 byte in the function sky2_get_rx_data_size(), the

Since you are using DSA, you will have DSA tags enabled on frames
to/from the switch. This adds an extra 8 byte header in the frame. My
guess is, it is this header, not the VLAN tag which is causing you MTU
issues.
But it is strange because, as I have said
