Kernel support for a dummynet option:
When a pipe or queue has the "noerror" attribute, do not report
drops to the caller (ip_output() and friends).
(2 lines to implement it, 2 lines to document it.)
This will let you simulate losses on the sender side as if they
happened in the middle of the network, i.e. with no explicit feedback
to the sender.
manpage and ipfw2.c changes to follow shortly, together with other
ipfw2 changes.
