SoapyUHD with N310 and with the Octoclock module

[tingjunchen]

1. For the N310 device with both mgmt_addr, addr, and second_addr args, would you recommend to include all the relevant interfaces in setting up the SoapyUHD device and separate the mgmt_addr from the (data) addr?

2. I cannot find any support for the case where multiple USRP devices are synced via the Octoclock module. Would it be possible to add this support so that SoapyUHD can be used in the case where multiple synced USRPs are used as a MIMO station?

Any suggestions and help would be appreciated. Thanks!
