Give Feedback Master Channel in Bonded Configurations

For PCIe*, both the PMA and PCS must be bonded. There is no need to specify the PMA Master Channel because of the separate Master CGB in the hardware. However, you must specify the PCS Master Channel through the Native PHY. You can choose any one of the data channels (part of the bonded group) as the logical PCS Master Channel.

Note: Whichever channel you pick as the PCS master, the fitter selects the physical CH1 or CH4 of a transceiver bank as the master channel. This is because the ASN and Master CGB connectivity only exists in the hardware of these two channels of the transceiver bank.
