Use the dev-level fci-info pciex_status; for example:

mercuryc4(MMB):$ fci-info pciex_status
fc
fc 					pciex_status = 0x27f00006 670040070
fc 				pciex_num_active_lanes : 0x8 8

Note that the output in the last column of the last line, "pciex_num_active_lanes", is "0x8 8", indicating that the PCIe connection between the SI FPGA and the Tachyon Fibre Channel controller is successfully increased from four to eight lanes. The output is "4" if Performance Accelerator is disabled.
