commit dbd726959cd08c33c7a0ebf8297445913b14605a
Author: Our Air Quality <address@hidden>
Date:   Thu Sep 21 10:36:21 2017 +0200

    [PATCH] Replace the OOSEQ max bytes and pbufs constants with functions.
    
    Some systems need to take into account an RX buffer pool size when
    advising an appropriate number of RX pbufs to queue on the ooseq
    list. For some systems there is a practical hard limit beyond which
    the rx pool becomes exhausted blocking reception of further buffers
    until some are freed.
    
    It also helps to be able to consider the available dynamic memory when
    advising an appropriate maximum number of bytes to buffer on the ooseq
    list.
    
    These decisions can also benefit from knowing the number already
    allocated on a particular pcb, so the ooseq tcp segement is passed to
    these functions. For example, if the system only wants to allow the
    total number of rx pbufs queued on all the ooseq lists to grow by one
    and a pcb already has two then it can return three for this call, but
    might return one for another call - supporting a greedy allocation
    strategy.
