 The NIC channel and the CMA channel are registered in the threads contexts.

+This blocking function transfer one container (4 Kbytes)  from the kernel chbuf defined by the NIC_RX channel registered in the calling thread context to an user buffer. The <buffer> argument is the container base address in user space.
 Several user threads can concurrently access the same chbuf, because the syscall handler takes the lock protecting the chbuf. It returns only when the container has been fully transfered.
 The calling thread exit if the buffer is not in user space, or if no allocated NIC_RX channel, or in case of timeout.
