In order for the network device ops get_stats call to be immutable, the handling of the default internal network device stats block has to be changed. Add a new helper function which replaces the old use of internal_get_stats. Note: change return code to make it clear that the caller should not go changing the returned statistics.

If segmentation offload is enabled by the host, we currently allocate maximum sized packet buffers and pass them to the host. This uses up 20 ring entries, allowing us to supply only 20 packet buffers to the host with a 256 entry ring. This is a huge overhead when receiving small packets, and is most keenly felt when receiving MTU sized packets from off-host. The VIRTIO_NET_F_MRG_RXBUF feature flag is set by hosts which support using receive buffers which are smaller than the maximum packet size. In order to transfer large packets to the guest, the host merges together multiple receive buffers to form a larger logical buffer. The number of merged buffers is returned to the guest via a field in the virtio_net_hdr. Make use of this support by supplying single page receive buffers to the host. On receive, we extract the virtio_net_hdr, copy 128 bytes of the payload to the skb's linear data buffer and adjust the fragment offset to point to the remaining data. This ensures proper alignment and allows us to not use any paged data for small packets. If the payload occupies multiple pages, we simply append those pages as fragments and free the associated skbs. This scheme allows us to be efficient in our use of ring entries while still supporting large packets. Benchmarking using netperf from an external machine to a guest over a 10Gb/s network shows a 100% improvement from ~1Gb/s to ~2Gb/s. With a local host->guest benchmark with GSO disabled on the host side, throughput was seen to increase from 700Mb/s to 1.7Gb/s. Based on a patch from Herbert Xu.

Each time we re-fill the recv queue with buffers, we allocate one too many skbs and free it again when adding fails. We should recycle the pages allocated in this case. A previous version of this patch made trim_pages() trim trailing unused pages from skbs with some paged data, but this actually caused a barely measurable slowdown.

Make pegasus driver not allocate a workqueue until the driver is bound to some device, which will need that workqueue if the device is brought up.

dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which should contain the length in bytes of the transferred data. This would be correct if reply was a u32 *. However it is a void * here, so we need to read the value at (reply+20) instead. The value at (reply+5) is usually 0xff0000, which is apparently 'large enough' and didn't cause any trouble until 2.6.27 where commit 427e59f0 Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Sat Mar 8 18:24:17 2008 -0600 [SCSI] make use of the residue value caused this to become visible through e.g. iostat -x .

Currently libata uses four methods to detect device presence. 1. PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

Commit 46abc021 ("phylib: give mdio buses a device tree presence") added a call to device_unregister() in a situation where the caller did not intend for the device to be freed yet, but apart from just unregistering the device from the system, device_unregister() does an additional put_device() that is intended to free it. The right function to use in this situation is device_del(), which unregisters the device from the system like device_unregister() does, but without dropping the reference count an additional time.
