Re: [Discuss-gnuradio] UHD Announcement - July 6th 2010

The make takes a device_addr_t which means you may pass in the formatted 
string or a device_addr_t dictionary object:

mimo_usrp::make("addr=192.168.10.11 192.168.20.11")

or

device_addr_t dev_addr;
dev_addr["addr"] = "192.168.10.11 192.168.20.11"
mimo_usrp::make(dev_addr);
