-/* The WRITE_BUFFER_SIZE value needs to be chosen such that if we set
- the socket send buffer size to '1', a write of this size on that
- socket will block.
-
- The Linux kernel imposes a minimum send socket buffer size which
- has changed over the years. As of Linux 3.10 the value is:
-
- 2 * (2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff)))
-
- which is attempting to make sure that with standard MTUs,
- TCP can always queue up at least 2 full sized packets.
-
- Furthermore, there is logic in the socket send paths that
- will allow one more packet (of any size) to be queued up as
- long as some socket buffer space remains. Blocking only
- occurs when we try to queue up a new packet and the send
- buffer space has already been fully consumed.
-
- Therefore we must set this value to the largest possible value of
- the formula above (and since it depends upon the size of "struct
- sk_buff", it is dependent upon machine word size etc.) plus some
- slack space. */
