Yeah, the driver tries to keep the DAC clock close to it’s max legal frequency
with the highest possible interpolation ratio from master_clock_rate.
That code doesn’t have any API access but I can show Sean how to hack it into
UHD if necessary.

Sean,
if I remember correctly, the filter configuration (whether or not a filter is
bypassed) is determined by the ratio of DAC rate to master-clock rate (the
interpolation that needs to happen inside the ad9361) thus, you can only
somewhat,
indirectly, control it by changing the master-clock
We'd like to bypass the Tx FIR filter and I'm wondering how to go about
this using the C++ api.
For the filter_base_info class there is the is_bypassed() function to read
the state, but no function to set it.
Should we be creating a new filter pointer with bypass set, and then using
it to
