Hi List, hi Richard,
Slight bump - we are now at 5.6Gbit. Same host hardware - 3.5GHz Athlon.
This is an incremental on top of the last patchset from this week which
tidies up further the SG and TSO/GSO code and enables it both way to the
extent possible.
Richard, I would like, if possible, to start working on cleaning this
up. IMHO it will be better to work off the last submitted patch version
and add TSO/GSO in a next revision after (and of course if) we have it
merged. TSO/GSO will drag a huge blob of ethtool (or mconsole) related
code to control it, it will be better if it comes as an incremental and
not with the core driver code.
Example:
aivanov@MonstrousNightmare:~$ iperf -c 192.168.125.118

aivanov@MonstrousNightmare:~$ iperf -s

I got the TSO and some offloads working for some (not all) cases of my
patchsets.
Preliminary speeds and feeds on iperf:
[ 4] local 192.168.98.1 port 5001 connected with 192.168.98.132 port

As a comparison - kvm/qemu on same machine does about a Gbit and vEth
to container does 20Gbit - so somewhere in between.
I am having some trouble with TSO and raw sockets. Once I figure out
what is going on (and hopefully fix it) there will be an updated
version which should take us into 4x what kvm/QEMU does on one CPU
networkwise.

Hi List, hi Richard,
I found a logical error in the SG code. This revision fixes that. No
other changes - the rest appears to work as it should in my testing.
Brgds,
A.
