I had been looking at /mboards/0/link_max_rate to determine if an X300 was
connected via 10 GigE or 1 GigE. However it seems like sometime between when
that was implemented for the X300 (
485ef414 ) and now (
edec40/host/lib/usrp/x300/x300_impl.cpp#L676 ) that was changed to always
return the 10 G rate even when connected via 1 G. Is there another way to
determine how an X300 is connected?
