Comment 2 Gary Thomas 2002-08-13 10:14:34 EDT
This failure happens because the logical network driver is trying to take
a packet (string of mbufs) and send it to the physical layer.  This is done
via a simple data structure of limited size.   This test program easily causes
that data structure to overrun, which is currently treated as an error.
Comment 3 Gary Thomas 2002-08-13 11:57:51 EDT
Made size of scatter-gather list configurable, with a slightly larger default.
