* be2net: remove BUG_ON() when be2net runs out of mccq wrbsSathya Perla2009-11-231-4/+85
| | | | | | | | | The driver can run out of mccq wrbs when completions don't arrive due to an unresponsive card. This must not hit a BUG_ON(); instead log a msg and return an error. Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | Sending config commands to be2 hardware before netdev_register is completed, is sometimes causing the async link notification to arrive even before the driver is ready to handle it.
