Subject: Maintain source addresses on radio->UART.
X-Git-Tag: tinyos/2.0.1~247
X-Git-Url: https://oss.titaniummirror.com/gitweb/?a=commitdiff_plain;h=cd0e5f9392936dfaa357848b3f3b119d94960d70;p=tinyos-2.x.git

Maintain source addresses on radio->UART.

Need to discuss with Jonathan how to handle UART->radio. Perhaps the AM
layer should take care of filling in source address, then the BaseStation
can just circumvent this and directly call into CC2420 stack?
