To wrap up this thread.. I just sent out a tentative patch with the first round of fixes to netdev. These fixes take care of the bare minimum of making sure we don't soft-lockup when the sink does not receive packets. I can still see at least 2 areas of improvement, that I'd like to address separately, since the changes are non-trivial and have to be done carefully 1. finer granularity of flow-control in vnet_start_xmit(): instead of doing a netif_stop_queue() when any single peer is congested, try to track flow-control for that peer only, and let the others continue Tx/Rx 2. better recovery from vnet_send_ack() failure: I have a somewhat odd printk there today, just to let the admin know that help is needed. I've tried calling ldc_disconnect() here, but it doesn't really reset the peer, though a module-reload fixes it. So what's needed is to trigger just the unregister/register of the problematic port, and this will need more than a few lines of change (I think it has to be triggered by ds?) I'll take a look at those two over the next few weeks, but didnt want to hold up these changes hostage while that's happening. --Sowmini -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
