* be2net: fix cmd-rx-filter not notifying MCCSathya Perla2011-08-031-0/+1
| | | | | | | | | | | Dave, I missed out on this line while composing the 4/6 patch from my yesterday's patchset ("[PATCH net-next 4/6] be2net: use RX_FILTER cmd to program multicast addresses"). As you've already queued up the patchset for net-next, I'm sending the fix in a separate patch. Pls apply. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

* 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().

* be2net: create/destroy rx-queues on interface open/closeSathya Perla2011-06-303-44/+111
| | | | | | | | | | | | | | | | | | 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.

For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.
