We are using LS1043A, PCIe Gen 2 interface is connected to Trident 2+ broadcom swithc. In LS1043A, Serdes configured as per below configuration of RCW[SRDS_PRTCL_S1] 


For PCIe, Gen 2 we will be configuring either RCW[SRDS_PRTCL_S1] as 1460 or 2460 (i.e, Lane C and lane D is configured as PCIe, Gen2?
