All, I've just found that read from /dev/bpfX never return EAGAIN/EWOULDBLOCK. It means that when you do a non blocking read and there is no data you will always get 0. Does it suppose work this way? A non blocking read from pipe return EAGAIN/EWOULDBLOCK if there is no data and pipe was opened as O_RDWR, and 0 when pipe was opened as O_RDONLY.
