Subject: r8169, enabling TX checksumming breaks things?
Date: Wed, 23 Sep 2009 09:15:27 +0300	[thread overview]
Message-ID: <200909230915.27854.denys@visp.net.lb> (raw)

Hi

Is it expected that:
1)TX checksumming is off by default
2)If i try to enable it over ethtool -K eth0 tx on , TCP sessions on proxy 
getting stuck, even in tcpdump looks everything fine and packets reaching 
destination, i don't understand what is a reason of failure.
Maybe if this feature supposed to not work - user must not be able just to 
turn it on?

Checksum OFF, connection established, no data received.

Checksum ON, connection established, no data received.

If required i can capture binary pcap files.
