When lan966x was receiving a frame, then it was building the skb and
after that it was calling dma_unmap_single with frame size as the
length. This actually has 2 issues:
1. It is using a length to map and a different length to unmap.
2. When the unmap was happening, the data was sync for cpu but it could
be that this will overwrite what build_skb was initializing.
The fix for these two problems is to change the order of operations.
First to sync the frame for cpu, then to build the skb and in the end to
unmap using the correct size but without sync the frame again for cpu.
