The 'n' interfaces are for netmap use and show up only if you have netmap support compiled into the kernel (which is the default for HEAD but not any stable/release branch). There is work in progress to move the 'n' interfaces to their own module so that they'll show up only if you load that extra module to get native netmap support for cxl/cxgbe. Regards, Navdeep
