I don't believe that this is fixed in later versions of the driver.
The problem is that when the interface loses link the transmit queue
can fill up. Once that happens the driver never gets any more calls
from the network stack to make it send packets. Pinging the interface
fixes it because the driver processes rx.and tx from the same context,
so when it receives a packet it starts transmitting again.
The patch that I sent fixes the problem by forcing the driver to
process the tx queue when ever links goes from down to up.
but on my production machine, when i see 'no buffer space available',
pinging the interface does not fixes it. Last time I tried to ping, ssh
to the machine, but machine stayed unavailable. Only `/etc/rc.d/netif
restart` from local console helped.
I will try to reproduce the situation on test machine. if this happens,
I will try the patch.
Thanks
