And note that sky2 doesn't have this problem. Does the broadcom do TSO?
And sky2 not? I noticed a much higher CPU load for sky2.
Yes the broadcoms (the revisions I have) do TSO and it is enabled
on both sides.
Which makes the mis-matched performance even stranger :)
Stranger still, with a mix of a 2.6.23-rc5ish kernel and a net-2.6.24 one
(pulled oh middle of last week?) I get link-rate and I see no asymmetry between
TCP_STREAM and TCP_MAERTS over an "e1000" link with no switch or tg3 with a
ProCurve on my rx2660's.
I can also run bw_tcp from lmbench 3.0a8 and get 106 MB/s.
I don't have a netgear switch to try in all this...
