* be2net: no need to query link statusSathya Perla2011-08-031-26/+11
| | | | | | | | | Change in the link status generates an MCC event. This is processed and netif_carrier_on/off is called accordingly. Don't need to query/store the link_status state. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* be2net: remove wrong and unnecessary calls to netif_carrier_off()Sathya Perla2011-08-031-2/+0
| | | | | | | | | | | | | 1) In be_probe(), as soon as the MCC Q is created a gratuitous link status event is received and processed. Accordingly netif_carrier_off/on() is called. The extra netif_carrier_off() call in probe can race with this and cause wrong state. 2) be_close() need not call netif_carrier_off(). It is OK to show the actual link state even when the device is administratively down. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* be2net: create/destroy rx-queues on interface open/closeSathya Perla2011-06-301-37/+68
| | | | | | | | | | | | | | | | | | On some skews, the BE card sends pause frames (and not drop pkts) if there are no more posted buffers available for packet reception. This behaviour has a side effect: When an interface is disabled, buffers are no longer posted on the corresponding RX rings. All broadcast and multicast traffic being received on the port will quickly fill up the PMEM and cause pause push back. As the PMEM is shared by both the ports, all traffic being received on the other (enabled) port also gets stalled. The fix is to destroy RX rings when the interface is disabled. If there is no RX ring match in the RXF lookup, the packets are discarded and so don't hog the PMEM. The RXQ creation cmd must now use MCC instead of MBOX as they are are called post MCC queue creation. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

* be2net: Fix to prevent flooding of TX queuePadmanabh Ratnakar2011-05-111-8/+12
| | | | | | | | | | | | Start/stop TX queue is controlled by TX queue "used" counter. It is incremented while WRBs are posted to TX queue and decremented when TX completions are received. This counter was getting decremented before HW is informed about processing of TX completions. As used counter is decremented, transmit function posts new WRBs and creates completion queue full scenario in HW.
