2011-09-27tcp: unalias tcp_skb_cb flags and ip_dsfieldEric Dumazet4-4/+5
struct tcp_skb_cb contains a "flags" field containing either tcp flags or IP dsfield depending on context (input or output path) Introduce ip_dsfield to make the difference clear and ease maintenance. If later we want to save space, we can union flags/ip_dsfield Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-27enic: Add support for port profile association on a enic SRIOV VFRoopa Prabhu4-96/+232
This patch touchs most of the enic port profile handling code. Tried to break it into sub patches without success. The patch mainly does the following: - Port profile operations for a SRIOV VF are modified to work only via its PF - Changes the port profile static struct in struct enic to a pointer. This is because a SRIOV PF has to now hold the port profile information for all its VF's - Moved address registration for VF's during port profile ASSOCIATE time - Most changes in port profile handling code are changes related to indexing into the port profile struct array of a PF for the VF port profile information Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: Sujith Sankar <ssujith@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: David S.

2011-09-27tcp: ECN blackhole should not force quickack modeEric Dumazet2-7/+17
While playing with a new ADSL box at home, I discovered that ECN blackhole can trigger suboptimal quickack mode on linux : We send one ACK for each incoming data frame, without any delay and eventual piggyback. This is because TCP_ECN_check_ce() considers that if no ECT is seen on a segment, this is because this segment was a retransmit. Refine this heuristic and apply it only if we seen ECT in a previous segment, to detect ECN blackhole at IP level.

2011-09-27sky2: manage irq better on single port cardstephen hemminger1-26/+59
Most sky2 hardware only has a single port, although some variations of the chip support two interfaces. For the single port case, use the standard Ethernet driver convention of allocating IRQ when device is brought up rather than at probe time. Also, change the error handling of dual port cards so that if second port can not be brought up, then just fail. No point in continuing, since the failure is most certainly because of out of memory. The dual port sky2 device has a single irq and a single status ring, therefore it has a single NAPI object shared by both ports.

2011-09-27xen/pciback: Add flag indicating device has been assigned by XenKonrad Rzeszutek Wilk1-0/+2
Device drivers that create and destroy SR-IOV virtual functions via calls to pci_enable_sriov() and pci_disable_sriov can cause catastrophic failures if they attempt to destroy VFs while they are assigned to guest virtual machines. By adding a flag for use by the Xen PCI back to indicate that a device is assigned a device driver can check that flag and avoid destroying VFs while they are assigned and avoid system failures.

Currently ehea ndo_get_stats can sleep in two places, in a hcall and in a GFP_KERNEL alloc, which is not correct.

2011-09-23net/fec: fix fec1 check in fec_enet_mii_init()Shawn Guo1-1/+1
In function fec_enet_mii_init(), it uses non-zero pdev->id as part of the condition to check the second fec instance (fec1). This works before the driver supports device tree probe. But in case of device tree probe, pdev->id is -1 which is also non-zero, so the logic becomes broken when device tree probe gets supported. The patch change the logic to check "pdev->id > 0" as the part of the condition for identifying fec1. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: David S.

2011-09-23net/fec: fec_reset_phy() does not need to always succeedShawn Guo1-8/+5
FEC can work without a phy reset on some platforms, which means not very platform necessarily have a phy-reset gpio encoded in device tree. Even on the platforms that have the gpio, FEC can work without resetting phy for some cases, e.g. boot loader has done that. So it makes more sense to have the phy-reset-gpio request failure as a debug message rather than a warning, and get fec_reset_phy() return void since the caller does not check the return anyway.
