tap: add Linux multiqueue support
This patch add basic multiqueue support for Linux. When multiqueue is needed, we will first check whether kernel support multiqueue tap before creating more queues. Two new functions tap_fd_enable() and tap_fd_disable() were introduced to enable and disable a specific queue. Since the multiqueue is only supported in Linux, return error on other platforms.
