real_num_rx_queues is defined in "include/linux/netdevice.h":
It requires CONFIG_SYSFS flag, which is enabled by default, but not
set in your config file.

Could you use default config and add hyperv drivers, then try again?

You must fix your driver to compile successfully under all possible configuration
combinations, not just the ones which are convenient for you to support.

I have submitted a patch to support compiling it without CONFIG_SYSFS flag.

Thanks,
