2010-02-18macvtap: add GSO/csum offload supportArnd Bergmann
Added flags field to macvtap_queue to enable/disable processing of virtio_net_hdr via IFF_VNET_HDR. This flag is checked to prepend virtio_net_hdr in the receive path and process/skip virtio_net_hdr in the send path. Original patch by Sridhar, further changes by Arnd.

2010-02-18net/macvtap: add vhost supportArnd Bergmann
This adds support for passing a macvtap file descriptor into vhost-net, much like we already do for tun/tap. Most of the new code is taken from the respective patch in the tun driver and may get consolidated in the future.

2010-02-18macvtap: rework object lifetime rulesArnd Bergmann
This reworks the change done by the previous patch in a more complete way. The original macvtap code has a number of problems resulting from the use of RCU for protecting the access to struct macvtap_queue from open files. This includes - need for GFP_ATOMIC allocations for skbs - potential deadlocks when copy_*_user sleeps - inability to work with vhost-net Changing the lifetime of macvtap_queue to always depend on the open file solves all these. The RCU reference simply moves one step down to the reference on the macvlan_dev, which we only need for nonblocking operations.

2010-02-17tg3: Enforce DMA mapping / skb assignment orderingMatt Carlson
Michael Chan noted that there is nothing in the code that would prevent the compiler from delaying the access of the "mapping" member of the newly arrived packet until much later. If this happened after the skb = NULL assignment, it is possible for the driver to pass a bad dma_addr value to pci_unmap_single(). To enforce this ordering, we need a write memory barrier. The pairing read memory barrier already exists in tg3_rx_prodring_xfer() under the comments starting with "Ensure that updates to the...".

2010-02-17net: bug fix for vlan + gro issueAjit Khaparde
Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

2010-02-17ipg: Remove device claimed by dl2k from pci id tableJeff Mahoney
This patch removes D-Link DGE-550T PCI ID (1186:4000) from the ipg driver. The ipg driver is for IP2000-based cards and the DGE-550T is a DL2000-based card. The driver loads and works for a few moments, but once a real workload is applied it stops operating. The ipg driver claimed this ID since it was introduced in 2.6.24 and it's forced many users to blacklist it. The correct driver for this hardware is the dl2k driver, which has been claiming this PCI ID since the 2.4 days. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: David S.
