=====================================================
If the packet type ID field in the Ethernet header is either ETH_P_PRP or
ETH_P_HSR, but it is not followed by an HSR tag, hsr_get_skb_sequence_nr()
reads an invalid value as a sequence number. This causes the above issue.
This patch fixes the issue by returning NULL if the Ethernet header is not
followed by an HSR tag.
