The first patch of this series improves the RX side. As it seems to be an expensive operation to read the RX timestamp for every frame, then read it only if it is required. This will give an improvement of ~70mbit on the RX side. The second patch stops using the packing library. This improves mostly the TX side as this library is used to set diffent bits in the IFH. If this library is replaced with a more simple/shorter implementation, this gives an improvement of more than 100mbit on TX side. All the measurements were done using iperf3.
v1->v2: - update lan966x_ifh_set to set the bytes and not each bit individually
