Noticed that the byte and packet count statistics are under- counting traffic handled by the DDP offload when there is more than one DDP completion processed in a single call to ixgbe_clean_rx_irq. This patch fixes that. I tried to optimize the setting of the rss value so that it only would have to be computed once, and only when there is a DDP completion present. Signed-off-by:

This patch adds debugfs support to the ixgbe driver to give users the ability to access kernel information and to simulate kernel events. The filesystem is set up in the following driver/PCI-instance hierarchy: <debugfs> |-- ixgbe |-- PCI instance | |-- attribute files Signed-off-by:

This change fixes the assumptions of the rate limiting code that previously assumed that each VF would only ever have 2 queues. This update makes it so that we now use a queues per pool value that is determined based on the VMDq feature mask. Signed-off-by:

The PF was not correctly registering any of its VLANs. As a result any VLAN tagged traffic from the VF would not be delivered to the PF because the VLAN was never assigned to the PF pool. In addition the VF was not allowed to receive traffic from VLAN 0 if it was allowed to receive untagged frames. This change corrects that so that it will correctly receive traffic from VLAN 0.

Added labels for site-local addresses (fec0::/10) and 6bone testing addresses (3ffe::/16) in order to depreference them. Note that the RFC introduced new rows for Teredo, ULA and 6to4 addresses in the default policy table. Some of them have different labels from ours. For backward compatibility, we do not change the "default" labels. Signed-off-by:

The scsi netlink code confuses the netlink port id with a process id, going so far as to read NETLINK_CREDS(skb)->pid instead of the correct NETLINK_CB(skb).pid. Fortunately it does not matter because nothing registers to respond to scsi netlink requests. The only interesting use of the scsi_netlink interface is fc_host_post_vendor_event which sends a netlink multicast message. Since nothing registers to handle scsi netlink messages kill all of the registration logic, while retaining the same error handling behavior preserving the userspace visible behavior and removing all of the confused code that thought a netlink port id was a process id. This was tested with a kernel allyesconfig build which had no problems. Cc: James Bottomley <James.Bottomley@parallels.com> Cc: James Smart <James.Smart@Emulex.Com> Signed-off-by:

Change various flows in the bnx2x driver which up until now flapped the link - these flows now benefit from the link flap avoidance mechanism. This includes the removal of the link reset made upon nic init, as it is possible the link is already active at that time. Signed-off-by:

Various flows in the bnx2x driver cause a link-flap - if the link is up, it would be toggled down (after a mac/phy reset) and then taken back up. In many of these cases, there is no need to do cause such a flap, as the associated flows should not actually affect the link. This patch adds the 'Link Flap Avoidance' mechanism, which allows the driver to better determine if a given flow requires a link change, and thus minimize the number of link flaps caused by the driver.

Pablo Neira Ayuso says: ==================== The following patchset contains four Netfilter updates, mostly targeting to fix issues added with IPv6 NAT, and one little IPVS update for net-next: * Remove unneeded conditional free of skb in nfnetlink_queue, from Wei Yongjun. * One semantic path from coccinelle detected the use of list_del + INIT_LIST_HEAD, instead of list_del_init, again from Wei Yongjun. * Fix out-of-bound memory access in the NAT address selection, from Florian Westphal. This was introduced with the IPv6 NAT patches. * Two fixes for crashes that were introduced in the recently merged IPv6 NAT support, from myself. ==================== Signed-off-by:

In order to lay the foundation for 1G EEE support, several segments of code which are common to both 1G and 10G EEE configurations were extracted from the 10G EEE configuration flow to their own functions. E.g., bnx2x_eee_initial_config, bnx2x_eee_advertise, bnx2x_eee_disable, etc. The rest of the EEE functions were relocated and placed in a single, continuous section of the file. Signed-off-by:

When a policy expiration is triggered from user space the request travels through km_policy_expired and ultimately into xfrm_exp_policy_notify which calls build_polexpire. build_polexpire uses the netlink port passed to km_policy_expired as the source port for the netlink message it builds. When a state expiration is triggered from user space the request travles through km_state_expired and ultimately into xfrm_exp_state_notify which calls build_expire. build_expire uses the netlink port passed to km_state_expired as the source port for the netlink message it builds. Pass nlh->nlmsg_pid from the user generated netlink message that requested the expiration to km_policy_expired and km_state_expired instead of current->pid which is not a netlink port number.

It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by:
