2009-04-02igb: add support for x2 link width configurationsAlexander Duyck
When device is on PCIe link trained as x2 the driver is currently reporting link width as "unknown". The original patch provided by Myron adds the x2 link support and my changes are cosmetic to clean up the readability of the conditional operators.

2009-03-21igb: cleanup tx dma so map & unmap use matching callsAlexander Duyck
The igb driver was using map_single to map the skbs and then unmap_page to unmap them. This update changes that so instead uses skb_dma_map and skb_dma_unmap. In addition the next_to_watch member of the buffer_info struct was being set uneccesarily. I removed the spots where it was set without being needed.

2009-03-21igb: rework igb_set_multi so that vfs are properly updatedAlexander Duyck
Currently if there are no multicast addresses programmed into the PF then the VFs cannot have their multicast filters reset. This change makes it so the code path that updates vf multicast is always called along with the pf updates.

2009-03-21igb: allow tx of pre-formatted vlan tagged packetsArthur Jones
When the 82575 is fed 802.1q packets, it chokes with an error of the form: igb 0000:08:00.1 partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. Thanks to Kand Ly <kand@riverbed.com> for discovering the issue and the coming up with a solution.

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.

2009-03-02igb: remove skb_orphan callsAlexander Duyck
Remove skb_orphan call from igb driver as it can cause multiple issues due to the fact that it is calling the desctructor and removing the skb from the socket prior to transmission. The call was added to improve performance but did so by allowing the skb to be removed from the socket which gave the socket more window space to transmit. The performance gain is not worth the extra problems that this kind of workaround can introduce as this could lead to a potential DoS if a UDP stream decided to monopolize the transmit path.

2009-02-15igb: use timecompare to implement hardware time stampingPatrick Ohly
Both TX and RX hardware time stamping are implemented. Due to hardware limitations it is not possible to verify reliably which packet was time stamped when multiple were pending for sending; this could be solved by only allowing one packet marked for hardware time stamping into the queue (not implemented yet). RX time stamping relies on the flag in the packet descriptor which marks packets that were time stamped. In "all packet" mode this flag is not set. TODO: also support that mode (even though it'll suffer from race conditions).
