Andrew,

There's a chance that the receive buffers are being consumed at the same 
rate as they are being replenished in ibmveth_replenish_task()... 
Meanwhile, the calls to schedule_replenishing() from ibmveth_poll() 
won't schedule another replenishing cycle (because the not_replenishing 
flag is zero), starving the buffers and making the adapter unable to 
receive packets unless the module is reloaded... Here's a small patch 
that will fix it by scheduling another replenishing task after toggling 
the not_replenishing flag.

Please apply.
