2010-08-08e100/e1000*/igb*/ixgb*: Add missing read memory barrierJeff Kirsher
Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.

2010-08-08ixgbe: fix build error with FCOE_CONFIG without DCB_CONFIGJohn Fastabend
Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause a build error. This resolves the build error by wrapping the fcoe.up in CONFIG_IXGBE_DCB ifdefs. Also frames were being priority VLAN tagged even without DCB enabled. This fixes this so that 8021Q priority tags are only added with DCB actually enabled.

Some ixgbe cards put an invalid VF device ID in the PCIe SR-IOV capability. The ixgbe driver is only valid for PFs or non SR-IOV hardware. It seems that the same problem could occur on igb hardware as well, so if we discover we are trying to initialize a VF in ixbge_probe or igb_probe, print an error and exit.

2010-07-19ixgbe: properly toggling netdev feature flags when disabling FCoEYi Zou
When FCoE is disabled, there is a race condition that FCoE offload is turned off but the FCoE protocol driver is still queuing I/O thinking offload support still exists. This patch toggles off corresponding FCoE netdev feature flags and notify the FCoE stack first, allowing FCoE protocol stack driver to update its flags upon NETDEV_FEAT_CHANGE so no I/O will be using offload. Also, indicate FCoE offload flags in vlan_features in ixgbe_probe once and do not toggle them in ixgbe_fcoe_enable/disable so when FCoE is created on the VLAN interface, vlan_transfer_features() would properly update the VLAN netdev features flag and notify the FCoE protocol driver for NETDEV_FEAT_CHANGE.

2010-07-07net: fix 64 bit counters on 32 bit archesEric Dumazet
There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

2010-07-02net: decreasing real_num_tx_queues needs to flush qdiscJohn Fastabend
Reducing real_num_queues needs to flush the qdisc otherwise skbs with queue_mappings greater then real_num_tx_queues can be sent to the underlying driver. The flow for this is, dev_queue_xmit() dev_pick_tx() skb_tx_hash() => hash using real_num_tx_queues skb_set_queue_mapping() ... qdisc_enqueue_root() => enqueue skb on txq from hash ... dev->real_num_tx_queues -= n ... sch_direct_xmit() dev_hard_start_xmit() ndo_start_xmit(skb,dev) => skb queue set with old hash skbs are enqueued on the qdisc with skb->queue_mapping set 0 < queue_mappings < real_num_tx_queues. When the driver decreases real_num_tx_queues skb's may be dequeued from the qdisc with a queue_mapping greater then real_num_tx_queues. This fixes a case in ixgbe where this was occurring with DCB and FCoE. Because the driver is using queue_mapping to map skbs to tx descriptor rings we can potentially map skbs to rings that no longer exist.

2010-06-13ixgbe: fix automatic LRO/RSC settings for low latencyAndy Gospodarek
This patch added to 2.6.34: commit f8d1dcaf88bddc7f282722ec1fdddbcb06a72f18 Author: Jesse Brandeburg <jesse.brandeburg@intel.com> Date: Tue Apr 27 01:37:20 2010 +0000 ixgbe: enable extremely low latency introduced a feature where LRO (called RSC on the hardware) was disabled automatically when setting rx-usecs to 0 via ethtool. Some might not like the fact that LRO was disabled automatically, but I'm fine with that. What I don't like is that LRO/RSC is automatically enabled when rx-usecs is set >0 via ethtool. This would certainly be a problem if the device was used for forwarding and it was determined that the low latency wasn't needed after the device was already forwarding. I played around with saving the state of LRO in the driver, but it just didn't seem worthwhile and would require a small change to dev_disable_lro() that I did not like. This patch simply leaves LRO disabled when setting rx-usecs >0 and requires that the user enable it again. An extra informational message will also now appear in the log so users can understand why LRO isn't being enabled as they expect. Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

2010-05-06ixgbe: Streamline MC filter setup for VFsGreg Rose
The driver was calling the set Rx mode function for every multicast filter set by the VF. When starting many VMs where each might have multiple VLAN interfaces this would result in the function being called hundreds or even thousands of times. This is unnecessary for the case of the imperfect filters used in the MTA and has been streamlined to be more efficient.

2010-05-06ixgbe: Remove unneeded register writes in VF VLAN setupGreg Rose
The driver is unnecessarily writing values to VLAN control registers. These writes already done elsewhere and are superfluous here. Signed-off-by: Greg Rose <gregory.v.rose@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-05-05ixgbe: Add boolean parameter to ixgbe_set_vmolrGreg Rose
Add a boolean parameter to ixgbe-set_vmolr so that the caller can specify whether the pool should accept untagged packets. Required for a follow on patch to enable administrative configuration of port VLAN for virtual functions.

2010-04-27ixgbe: disable MSI-X by default on certain Cisco adaptersNicholas Nunley
Due to an errata in 82598 parts MSI-X needs to be disabled in certain ixgbe devices designed to transfer peer-to-peer traffic on the PCIe bus. This patch sets the default interrupt type to MSI rather than MSI-X for specific Cisco ixgbe adapters.
