Subject: [PATCH] network: (merges !424) Align error-model-test-suite with
 previous commit

Default size of a DropTailQueue is "100p" and error-model-test-suite calls
Send directly (rather than relying on flow control).  Previously, the
rest of the packets would be sent instantly, but previous commit fixes
that bug, so this commit makes the buffer large enough to hold all packets
