* knet will read data here to send to the other hosts
* and will write data received from the network.
* Each data packet can be of max size KNET_MAX_PACKET_SIZE!
* Applications using knet_send/knet_recv will receive a
* proper error if the packet size is not within boundaries.
* Applications using their own functions to write to the
* datafd should NOT write more than KNET_MAX_PACKET_SIZE.
*
* Please refer to handle.c on how to set up a socketpair.
*
* datafd can be 0, and knet_handle_add_datafd will create a properly
* populated socket pair the same way as ping_test, or a value
* higher than 0. A negative number will return an error.
* On exit knet_handle_free will take care to cleanup the
* socketpair only if they have been created by knet_handle_add_datafd.
*
* It is possible to pass either sockets or normal fds.
* User provided datafd will be marked as non-blocking and close-on-exit.
*
* *channel - This value has the same effect of VLAN tagging.
* A negative value will auto-allocate a channel.
* Setting a value between 0 and 31 will try to allocate that
* specific channel (unless already in use).
*
* It is possible to add up to 32 datafds but be aware that each
* one of them must have a receiving end on the other host.
*
* Example:
* hostA channel 0 will be delivered to datafd on hostB channel 0
* hostA channel 1 to hostB channel 1.
*
* Each channel must have a unique file descriptor.
*
* If your application could have 2 channels on one host and one
* channel on another host, then you can use dst_host_filter
* to manipulate channel values on TX and RX.
*
* knet_handle_add_datafd returns:
*
* 0 on success
* *datafd will be populated with a socket if the original value was 0
* or if a specific fd was set, the value is untouched.
* *channel will be populated with a channel number if the original value
