Previously I was unable to log into linux due to the boot loop.

I am able to now log into linux, but only through Console JTAG
I can NOT however, log in via SFP or the 1Gb ethernet. This whole
problem started after I tried to upload an FPGA bitstream to the
ettus, is it possible the x410 relies on the FPGA bitstream to
communicate over SFP/1 Gb ethernet at all?
If the implementation is like other, similar, radios, then, yes. The SFP
10G implementation MAC is done in the FPGA code, and if
that FPGA code is not working, then that would cause the SFP comms to
not work. I'm not sure on the X410 whether the
1G RJ-45 management port is "hardware inherent" or not.
