This change is meant to just clean-up a number of function calls that were made at the end of the Rx clean-up path by combining them into a single function call.

This change makes it so that we no longer use header split. The idea is to reduce partial cache line writes by hardware when handling frames larger then header size. We can compensate for the extra overhead of having to memcpy the header buffer by avoiding the cache misses seen by leaving an full skb allocated and sitting on the ring.

This change is meant to improve performance on systems that do not require the DMA unmap calls. On those systems we do not need to make use of the unmap address for Tx or the unmap length so we can drop both thereby reducing the size of the Tx buffer info structure. In addition I have changed the logic to check for unmap length instead of unmap address when checking to see if a buffer needs to be unmapped from DMA use. The reasons for this change is that on some platforms it is possible to receive a valid DMA address of 0 from an IOMMU.

Instead of storing the RSS key as a character array we can simplify the configuration by making it a u32 array. This allows us to just write one value per register without any unnecessary operations to construct the value. This change will produce the same exact key, the only difference is that I translated the u8 array to a u32 array which will be correctly ordered on writes to hardware by the cpu_to_le32 operations that are built into the writel calls.

This patch cleans up our RSS indirection table configuration so that we generate the same table regardless of CPU endianness. In addition it changes the table setup so that instead of doing a modulo based setup it is instead a divisor based setup. The advantage to this is that we should be able to take the Rx hash and compute the Rx queue with very little CPU overhead if needed.

This change makes it so that Tx cleanup is done in a do/while loop instead of a for loop.

This change removes the code that was doing the NUMA allocations for the q_vectors, rings, and ring resources.

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.

由 Mel Gorman 提交于
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 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.

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.
