This fixes some issues with the 2021.1 version of the 10 GbE IP. In the
new version, link status is sporadically detected by the Xilinx IP when
nothing is connected to the port. Also, when the SFP is inserted, the
link status goes up and down multiple times. This change fixes this by
adding a counter and only considering it "linked" when the link has
been stable for some amount of time.

This adds the ability to do IP generation and FPGA builds using the
--jobs (-j) option with Make. For example, rather than generating each
IP one after another, you can generate up to N at a time using N Vivado
instances. This greatly reduces the IP generation time. Similarly,
parallel jobs can be used to easily build different FPGA variants
simultaneously.
Because FPGA builds can consume a lot of memory, care must be taken to
ensure that the number of jobs is not too high for the amount of memory
available.
New IP make targets were added for each USRP so that IP can be built
separately from the FPGA. The IP targets are now a dependency on each
FPGA target.
For example, you can generate the IP for X310 using 4 parallel jobs
using the following command:
make -j4 X310_IP
Or, build two X310 bitstreams simultaneously:
make -j2 X310_XG X310_HG
