Hi, all:
    When i read the source code of ovs, i found the userspace receives
netlink message by epoll. But in the explanition of dpif.h, datapath starts
many threads to receiving netlink.
    Could anybody give me a definite answer that how does the userspace and
kernel space receive netlink messages.
