Oops, I meant the ML115, not 110. My mistake, so we do have identical 
systems..

You are correct. But that removed xen-utils, and now I no longer have 
'xm' and 'xentop'? Re-installing xen-utils will, of course, remove 
xenstore-utils. Anyway, I pasted the output of xenstore-ls below.

Mine is also from etch-backports

My mistake again, tso is off and can't be enabled manually with ethtool.

Here is the output of xenstore-ls:
0 = ""
backend-id = "0"
mac = "00:04:fc:40:e4:22"
handle = "0"
state = "4"
backend = "/local/domain/0/backend/vif/12/0"
tx-ring-ref = "15992"
rx-ring-ref = "15960"
event-channel = "7"
feature-no-csum-offload = "0"
feature-sg = "1"
feature-gso-tcpv4 = "0"
request-rx-copy = "1"
feature-rx-notify = "1"

Any idea why my tso is disabled and yours not? Btw, I'm happy with the 
results so far, so if it's too much trouble to get this working, we can 
leave this one alone. I guess it's my problem the system / kernel 
doesn't support tso, it's just strange that we both test on the same 
system with different results.
