 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:
