Hi,

supported media support is reported as:
        media 1000BASE-SGMII
        media 1000BASE-KX
        media 10GBASE-KR
        media 10GBASE-CR1
        media 10GbaseSR
        media 10GbaseLR
        media 1000baseT
        media autoselect

My assumption is 10GBASE-CR1 is full-duplex by default:
