Greetings,
I've been a happy LVS-NAT user for many years now. I am hoping to migrate
to newer hardware, but have been having issues getting LVS-NAT to work
with a Broadcom NetXtreme II BCM5709 card. The symptom is very poor
network performance. Traffic is able to pass through the NAT, but it is
brutally slow. Google is my friend and I found this:

The last suggestion is to use an EEPro1000 and that is what I have been
doing for these past years and haven't seen any issues.
Unfortunately, my newer hardware has a broadcom, so I have been attempting
to make it work again. I have a situation were I can actively test this
issue and attempt to get to the root of the problem if anybody here is
interested?
I am using stock RHEL6.3 64bit, Dell PowerEdge R510 with all firmware/BIOS
updates applied.
I tried the disable_msi=1 module option to bnx2 and that did not help.
I fired up wireshark on my laptop while attempting to reach the IPVS
cluster and get tons of:
Reassembled PDU in frame: 1969
TCP Retransmission [TCP Segment of a reassembled PDU]
Any ideas? Or I should just save the trouble and purchase a EEPro for the
machine? :)
thank you,
daryl
