Summary
Ref: https://man7.org/linux/man-pages/man7/packet.7.html
We should either set protocal when creating socket or binding, otherwise
we cannot capture any packet.
Impact
The netpkt tool will receive all types of Ethernet messages.
Testing
Open the compilation option CONFIG_EXAMPLES_NETPKT and set up the SIM environment. Use
netpkt - vrto receive messages at the SIM and send messages to the SIM at the host. Check the reception of SIM terminal. The result verifies that netpkt receives normally.
