I was able to get this working by defining CONFIG_CMD_NET in mx6ul_14x14_evk.h manually like so:

#ifndef CONFIG_CMD_NET
#define CONFIG_CMD_NET
#endif

I'm not sure how you're supposed to configure this though. It seems like normally it would be under "Command Line Interface" in the uboot-menuconfig however this option is not available in the uBoot version supplied by NXP.

Hopefully that's a workaround for you as well, but I'd like to know how we're supposed to enable this in the buildroot environment.

Correction. The change required in the same file is:

#define CONFIG_FEC_ENET_DEV 0

Still not sure how to configure this without changing the header file manually
