links incorrectly to the XU216-512-FB236 Datasheet
Inside this linked datasheet for the XU216-512-FB236 device, there are notes that this device features RGMII support (GigE) - same as the XE216-512-FB236 device ?? Suspecting this datasheet is in error and is for the XE216-512-FB236 device.
See here for another document for the XU216-512-FB236 Datasheet which does NOT mention the RGMII and appears to be correct on the features:

Also, the following webpage:

appears to exclude many of the permutations for the new XCORE-200 series (ie. FB236 BGA packaged devices). Any reason for the exclusions ?
