AD9371 eval PCB JESD204B interface

On the AD9371 eval PCB I noticed 4 JESD Rx lines and 4 JESD Tx lines/lanes are used to support only 2 Tx and 2 Rx..  Are you sending only I or Q on each line? or are those being used for the alternate receivers (sniffer or observation Rx)?

 

If so, can the I/Q be muxed onto a single JESD so that I can use only 4 JESD lanes to talk to 2 AD9371's?  Ideally I'd like to use 4+ AD9371, so looking for a way to keep the lane count reasonable.
