| * igb: Prevent dropped Tx timestamps via work items and interrupts.Matthew Vick2012-09-171-7/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | In rare circumstances, it's possible a descriptor writeback will occur before a timestamped Tx packet will go out on the wire, leading to the driver believing the hardware failed to timestamp the packet. Schedule a work item for 82576 and use the available time sync interrupt registers on 82580 and above to account for this.

* netvm: propagate page->pfmemalloc from skb_alloc_page to skbMel Gorman2012-08-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

| * igb, ixgbe: netdev_tx_reset_queue incorrectly called from tx init pathJohn Fastabend2012-05-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | igb and ixgbe incorrectly call netdev_tx_reset_queue() from i{gb|xgbe}_clean_tx_ring() this sort of works in most cases except when the number of real tx queues changes. When the number of real tx queues changes netdev_tx_reset_queue() only gets called on the new number of queues so when we reduce the number of queues we risk triggering the watchdog timer and repeated device resets. So this is not only a cosmetic issue but causes real bugs. For example enabling/disabling DCB or FCoE in ixgbe will trigger this.

* net: Fix issue with netdev_tx_reset_queue not resetting queue from XOFF stateAlexander Duyck2012-03-131-1/+2
| | | | | | | | | | | | | | | | We are seeing dev_watchdog hangs on several drivers. I suspect this is due to the __QUEUE_STATE_STACK_XOFF bit being set prior to a reset for link change, and then not being cleared by netdev_tx_reset_queue. This change corrects that. In addition we were seeing dev_watchdog hangs on igb after running the ethtool tests. We found this to be due to the fact that the ethtool test runs the same logic as ndo_start_xmit, but we were never clearing the XOFF flag since the loopback test in ethtool does not do byte queue accounting.
