Thanksalot for quick response Alexander.
I did use the same config file mentioned in Linaro AOSP build page.
I am now pondering whether to check the AOSP ICS sources used by Linaro...but usb-ethernet speed related stuff shouldnot be affected by anything in framework/userspace.... I use iperf to measure network throughput .
Hence again I suspect kernel changes

what is the pinned manifest should be what is in the build.

Have you double checked that you use the same config?
