[PATCH] dts: avoid Scapy MAC resolution in Rx split test

[PATCH] dts: avoid Scapy MAC resolution in Rx split test

[Thomas Monjalon]

The test gets the Ethernet header length from Scapy with len(Ether()).

When building DTS API documentation, Sphinx imports the test module
and shows this warning:
WARNING: MAC address to reach destination not found. Using broadcast.

Use a dummy MAC address so Scapy no longer performs
destination resolution during import.

Fixes: 01c70544cffd ("dts: add selective Rx tests")
