TCP/IP subsystem, nios2 & uCLinux

I'm in the early stages of an embedded project using the nios2 cyclone, and I'd love to use the Microtronix uCLinux distro with it. However, in looking through the driver code, I'm a little confused as to the workings of the TCP/IP subsystem. Namely, I've seen mention of the 'Plugs' embedded TCP/IP ss. I specifically do NOT want to use Plugs for this project. So, two questions: does the Microtronix distro use Plugs, and, if so, can this be changed to use the standard *NIX TCP subsystem?

Any help would be appreciated,
