That behavior of glibc is incorrect, I know about it, and I explained
all this to Uli Drepper some time ago and he fixed it.
Current glibc should not be doing this. If it still is, since Uli
understood my arguments, it probably just slipped under the rug.
Tell me this so I can take care of it.
What the glibc code was doing was mirroring the input packet parameters
(saddr/daddr/if/etc.) into what it used for the output packet sends.
