    I don't know what I was thinking two years ago when I answered that question, but of course it doesn't sound reasonable at all to use 4 out of 6 available SerDes lanes for PCIe, and also use 2x SATA and GbE from the P1022 which requires 3 more SerDes lanes, adding up to 7 required SerDes lanes in total.
