[PATCH 11/11] net/enetfec: add software packet type parsing and cleanup

[Hemant Agrawal]

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.
