It would be perfectly reasonable (and fairly straightforward) to update
libpcap to be able to filter on the Ethernet address in DLT_LINUX_SLL or
DLT_LINUX_SLL2 mode. There are already filters that match other offsets in
the SLL or SLL2 header. However, I don't think it could be done on live
captures, only against a savefile.
