Added note: PCIe revisions 1 and 2 are supported. Anything revision 3 will simply reduce back to a gen. 1 or 2 speed. Even gen. 1 (revision 1) supports 2.5GT/s (after 8b/10b encoding, but not including other overhead, this means a single lane of revision 1 supports 2Gb/s…revision 2 is twice as fast as revision one). Basically a single lane at the slowest speed would support a single gigabit. I do not know how the bridge would set up (it isn’t a typical PCIe endpoint device) at the non-Jetson end, but it might show as only achieving revision 2 speeds (or even revision 1), but regardless of this the speed exceeds gigabit requirements.
