transceiver: reroute UHD messages to logging facility
Pipe the following uhd message types to standard warning levels (INFO, WARN, ERROR) respectively. Ignore fastpath logging messages and, instead, catch them from the asynchronous device interface. enum type_t{ status = 's', warning = 'w', error = 'e', fastpath= 'f' }; Signed-off-by: Thomas Tsou <ttsou@vt.edu>
