[linux-dvb] What is the MAC of a DVB card?

[CityK]

There is an article in the wiki: 
http://www.linuxtv.org/wiki/index.php/InternetDVB

In addition, there is a brief note (that may help provide an 
explanation) in some of the B2C2 based device articles as to why they 
are listed as network controllers: 
http://www.linuxtv.org/wiki/index.php/TechniSat_Air2PC-ATSC-PCI#Why_are_they_listed_as_a_.22network_controller.22_and_not_a_.22multimedia_controller.22_in_the_output_of_dmesg_or_lspci.3F

in essence - similar to a network controller -- receive and demodulate 
RF signals.
