This patch adds software-based parsing for Ethernet packet types, specifically identifying IPv4 and IPv6 packets. This is a temporary solution until hardware-based parsing is implemented.
Additionally, variable declarations in `enetfec_recv_pkts()` are reordered to follow reverse Christmas tree style for better readability.
