[USRP-users] Vivado license for 10 GbE

Hey everyone,

Upon building my own custom RFNoC images for an X310 using Vivado GUI, I'm
getting a critical warning stating the following: "Evaluation License
Warning: This design contains one or more evaluation cores that will cease
to function after a certain period of time. This design should NOT be used
in production systems". It then mentions that the "ten_gig_eth_pcs_pma" IP
core was generated using a design_linking license.

Nevertheless, I found this Xilinx's AR
<https://www.xilinx.com/support/answers/68203.html> that says this error
will appear when using both BASE-R and BASE-KR cores, but that the BASE-R
one is actually free and the error message can be dismissed. I checked the
sources list and it appears that Ettus are indeed using a BASE-R IP core,
but I just wanted to make sure: can I keep generating bitstreams without
fearing the Ethernet interfaces to stop working after they run for a while?

Thanks in advance,

Leo
