* e1000e/igb/ixgbe: Don't report an error if devices don't support AERFrans Pop2009-10-021-11/+2
| | | | | | | | | | | The only error returned by pci_{en,dis}able_pcie_error_reporting() is -EIO which simply means that Advanced Error Reporting is not supported.

* igb: Record host memory receive overflow in net_statsJesper Dangaard Brouer2009-05-261-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Based on previous patch from Jesper Dangaard Brouer. The RNBC (Receive No Buffers Count) register for the 82576, indicate that frames were received when there were no available buffers in host memory to store those frames (receive descriptor head and tail pointers were equal). The packet is still received by the NIC if there is space in the FIFO on the NIC. As the RNBC value is not a packet drop, the driver stores this value in net_stats.rx_fifo_errors to indicate that there were no system buffers available for the incoming packet. Actual dropped packets are counted in the MPC value. Saving the stats in dev->net_stats makes it visible via /proc/net/dev as "fifo", and thus viewable to ifconfig as "overruns" and 'netstat -i' as "RX-OVR". The Receive No Buffers Count (RNBC) can already be queried by ethtool -S as "rx_no_buffer_count".

It counts the number of packets dropped by a queue due to lack of descriptors available. Notice RQDPC (Receive Queue Drop Packet Count) stats only gets incremented, if the DROP_EN bit it set (in the SRRCTL register for that queue). If DROP_EN bit is NOT set, then the some what equivalent count is stored in RNBC (not per queue basis). The RQDPC register is only 12 bit, thus the precision might suffer due to overrun in-netween the watchdog polling interval.

| * igb: remove ASPM L0s workaroundAlexander Duyck2009-03-141-24/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The L0s workaround should be moved into a pci quirk and so it is not necessary in the driver. This update removes the L0s workaround from the igb driver. This was the second half of the PCI quirk patch that Matthew Wilcox did not pick up when he picked up the quirk patch.

* | igb: correct typo that was setting vfta mask to 1Alexander Duyck2009-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch corrects a typo that was doing a less than comparison instead of a left shift due to the fact that I didn't get enough <'s in there. This resolves an issue in which vlans were not functioning correctly.
