net: hsr: Fix PRP duplicate detection
Add PRP specific function for handling duplicate
packets. This is needed because of potential
L2 802.1p prioritization done by network switches.
The L2 prioritization can re-order the PRP packets
from a node causing the existing implementation to
discard the frame(s) that have been received 'late'
because the sequence number is before the previous
received packet. This can happen if the node is
sending multiple frames back-to-back with different
priority.
