This is cleaner than rc.local and the ethtool support in the network up/down
scripts is completely broken on RHEL (it only supports setting duplex and
speed).

Hi Jesse,
The issue persists in all kernels on the 2.6 branch. I've not experienced it
with 3.x kernels but my scripts have disabled TX checksumming since I first
came across the issue.
The problem is that many people run VMs to support "legacy" systems on new
high-capacity hardware or in prod

Sorry Sheili,
I don't understand exactly what you are asking?
Also please reply to the list rather than directly to me.
Thanks,

disable hardware tx checksum
offload on F5's LTM VE.
I can only comment from experience - if that's not good enough then I don't
know what else I can offer.

Sheili,
A particular case to be aware of is when combining Linux bridging with 802.1q
vlans. Hardware tx checksum offload does not work properly in this scenario, so
it is advisable to disable tx checksum offloading in virtual machines which
connect to vifs mapped to a vlan or a trunk port to
When you "enable" tx checksum on the vm you are actually enabling "tx checksum
offloading". That is the vm delegates this to the switch. OVS doesn't so your
syn is dropped by the receiver.

I have a working patch for Wheezy which I am currently using in our test
environment.
It selectively applies the Git commits in support of the 3.1 kernel made since
1.2.2.
To use the patch:
apt-get install linux-source-3.1 linux-headers-3.1.0-1-all
openvswitch-datapath-source
cd /usr/src
tar j
