F-tile FHT 400GE lane swap

Hi！

we are using AGIB027R29A1E2VB FHT for 400GE-4.

when we using （0,1,2,3）-> (0,1,2,3) FPGA design project receive an error ：

QSFP112_RX0 -> FHTL12A_RX_CH0

QSFP112_RX1 -> FHTL12A_RX_CH1

QSFP112_RX2 -> FHTL12A_RX_CH2

QSFP112_RX3 -> FHTL12A_RX_CH3

QSFP112_TX0 -> FHTL12A_TX_CH0

QSFP112_TX1 -> FHTL12A_TX_CH1

QSFP112_TX2 -> FHTL12A_TX_CH2

QSFP112_TX3 -> FHTL12A_TX_CH3

but we using Inverse order(0,1,2,3) ->(3,2,1,0) FPGA design project works

QSFP112_RX0 -> FHTL12A_RX_CH3

QSFP112_RX1 -> FHTL12A_RX_CH2

QSFP112_RX2 -> FHTL12A_RX_CH1

QSFP112_RX3 -> FHTL12A_RX_CH0

QSFP112_TX0 -> FHTL12A_TX_CH3

QSFP112_TX1 -> FHTL12A_TX_CH2

QSFP112_TX2 -> FHTL12A_TX_CH1

QSFP112_TX3 -> FHTL12A_TX_CH0

after i check 400GE-4 example. i found example project using Inverse order(0,1,2,3) ->(3,2,1,0).

is that correct?

thanks !
