Is 100Mb half duplex Ethernet support on the new T series CPU's, such as the T4240?

When trying to set the Ethernet mode to 100Mb half duplex in Gentoo Linux, it sets to 10Mb full duplex.

Looking at the NXP driver, we found this piece of code commented out.


if (strstr(char_prop, "sgmii"))                mac_dev->if_support &= ~(SUPPORTED_10baseT_Half |                                        SUPPORTED_100baseT_Half);

When this code was added back in, we see this error generated.
