"No buffer space available" problem still exist.

Note that this doesn't necessarily indicate a lack of memory.  It's
very likely that the output queue is at the # of packets limit.  If
I'm reading the code correctly, that's 256.  In other words, probably
adding a new packet fails because the queue is at the defined limit,
not because memory for the packet can't be obtained.
