This has been tested in a local 8b_tx -> 1b_rx loopback app only but results are positive so far and it passes at 70MHz min thread speed so just meets our goal of 75MHz. The wrapping logic took this from 60 to 70MHz.
Captured in #88
It has been verified using the tests/bringup app (ping) also in hw.
This still needs the sim/hw tests extended and IFG calculations done as well as extending the docs.
