Well specifically if_ether.h says GPLv2+ so it's OK for QEMU.
Do you mean for some other non GPL app?

Ignore QEMU for the moment.

The headers say they are BSD licensed... but they include a GPLv2+
header.

Above is a bit misleading.  To be precise, they don't include a GPLv2+
header. One header merely includes this line:
#include <linux/if_ether.h>
