Hi Emil, Thanks for your time. As part of trying to quickly recover from a failed NIC driver (in this case e1000), we've been trying to measure the time from device reset to when packets start flowing. Our measurements show the time to be around 1.8s. We are just trying to figure out where all the time is going and thought perhaps the autoneg and training had something to do with it.
We did hack the driver to force the speed and the master/slave mode and I will post the diff as soon as I can get it. Now, I have a slightly different question for you and hopefully you can help us out. There appears to be rx descriptor caches that are kept in the NIC device. I know there is a way to flush used descriptors, but is there a way to purge the unused cached descriptors without having to do a device reset. This might be unusual, but maybe necessary if we need to change the locations of the buffers and need to tell the device to re-fetch the descriptors. I tried looking at the manual and can't find anything on this.
