Hi Justin,
Thanks. If we need to create our own queues, we need to
find out whether there is space in the kernel queue before sending a packet.
So, need to use the netdev_send_wait( ) function before using netdev_send( ) to
send a packet. The netdev_send_wait( ) function uses looping to check if there
is buffer space. Hence, if the single thread is held up in the loop, wont it
affect the incoming packets at the input port? How will it receive new packets
at the same time it is in the loop? Please correct me if I am wrong.
