Subject: Multicast and hardware checksum
Date: Fri, 08 Jun 2007 01:33:14 +0300 [thread overview]
Message-ID: <466887AA.800@ev-en.org> (raw)
Hello,
I have a machine on which I have an applications that sends multicast
through eth interface with hardware tx checksum enabled. On the same
machine I have mrouted running that routes the multicast traffic to a
set of ppp interfaces. The packets that are received by the client have
their checksum fixed on some number which is incorrect. If I disable tx
checksum on the eth device the packets arrive with the proper checksum.
I still haven't followed the code paths to see how to fix this, maybe
someone knows the relevant code and can find it faster.
Baruch
