git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-11 This series contains updates to igb, i40e and i40evf. Todd makes a change to igb to un-hide invariant returns by getting rid of the E1000_SUCCESS define and converting those returns to return 0. Jacob separates the hardware logic from the set function, so that we can re-use it during a ptp_reset in igb. This enables the reset to return functionality to the last know timestamp mode, rather than resetting the value. Ashish implements context flags for headwb and headwb_addr so that we do not have to keep them always enabled. Shannon updates the admin queue API for the new firmware, which adds set_pf_content, nvm_config_read/write, replaces set_phy_reset with set_phy_debug and removes nvm_read/write_reg_se. Cleans up the driver to use the stored base_queue value since there is no need to read the PCI register for the PF's base queue on every single transmit queue enable and disable as we already have the value stored from reading the capability features at startup. Anjali changes the notion of source and destination for FD_SB in ethtool to align i40e with other drivers. Adds flow director statistics to the PF stats. Fixes a bug in ethtool for flow director drop packet filter where the drop action comes down as a ring_cookie value, so allow it as a special value that can be used to configure destination control. Mitch fixes the i40evf to keep the driver from going down when it is already in a down state. This prevents a CPU soft lock in napi_disable(). Also change the i40evf to check the admin queue error bits since the firmware can indicate any admin queue error states to the driver via some bits in the length registers. Neerav separates out the DCB capability and enabled flags because currently if the firmware reports DCB capability the driver enables I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver inserts a tag when transmitting a packet from the port even if there are no DCB traffic classes configured at the port. So by adding the additional flag, I40E_FLAG_DCB_CAPABLE, that will be set when the DCB capability is present and the existing enabled flag will only be set if there are more than one traffic classes configured at the port. Greg fixes the i40e driver to not automatically accept tagged packets by default so that the system must request a VLAN tag packet filter to get packets with that tag. Greg also converts i40e to use the in-kernel ether_addr_copy() instead of mempcy(). Jesse removes the FTYPE field from the receive descriptor to match the hardware implementation. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Since the VF really can't do much, we just print the message and depend on the PF driver to clear things up on our behalf.

2014-06-11net/mlx4_core: Keep only one driver entry release mlx4_privWei Yang
Following commit befdf89 "net/mlx4_core: Preserve pci_dev_data after __mlx4_remove_one()", there are two mlx4 pci callbacks which will attempt to release the mlx4_priv object -- .shutdown and .remove. This leads to a use-after-free access to the already freed mlx4_priv instance and trigger a "Kernel access of bad area" crash when both .shutdown and .remove are called. During reboot or kexec, .shutdown is called, with the VFs probed to the host going through shutdown first and then the PF. Later, the PF will trigger VFs' .remove since VFs still have driver attached. Fix that by keeping only one driver entry which releases mlx4_priv.

2014-06-11net/mlx4_core: Fix SRIOV free-pool management when enforcing resource quotasJack Morgenstein
The Hypervisor driver tracks free slots and reserved slots at the global level and tracks allocated slots and guaranteed slots per VF. Guaranteed slots are treated as reserved by the driver, so the total reserved slots is the sum of all guaranteed slots over all the VFs. As VFs allocate resources, free (global) is decremented and allocated (per VF) is incremented for those resources. However, reserved (global) is never changed. This means that effectively, when a VF allocates a resource from its guaranteed pool, it is actually reducing that resource's free pool (since the global reserved count was not also reduced). The fix for this problem is the following: For each resource, as long as a VF's allocated count is <= its guaranteed number, when allocating for that VF, the reserved count (global) should be reduced by the allocation as well. When the global reserved count reaches zero, the remaining global free count is still accessible as the free pool for that resource. When the VF frees resources, the reverse happens: the global reserved count for a resource is incremented only once the VFs allocated number falls below its guaranteed number.

Select the appropriate hw mtu index and initial sequence number to optimize hw memory performance. Add new cxgb4_best_aligned_mtu() which allows callers to provide enough information to be used to [possibly] select an MTU which will result in the TCP Data Segment Size (AKA Maximum Segment Size) to be an aligned value. If an RTR message exhange is required, then align the ISS to 8B - 1 + 4, so that after the SYN the send seqno will align on a 4B boundary. The RTR message exchange will leave the send seqno aligned on an 8B boundary. If an RTR is not required, then align the ISS to 8B - 1. The goal is to have the send seqno be 8B aligned when we send the first FPDU.

2014-06-10iw_cxgb4: Allocate and use IQs specifically for indirect interruptsHariprasad Shenai
Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA RXQs, which also handle direct interrupts for offload CPLs during RDMA connection setup/teardown. The intended T4 usage model, however, is to have indirect interrupts flow through dedicated IQs. IE not to mix indirect interrupts with CPL messages in an IQ. This patch adds the concept of RDMA concentrator IQs, or CIQs, setup and maintained by the LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will flow through the LLD's RDMA RXQs, and CQ interrupts flow through the CIQs. Design: cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs are sized according to the max available CQs available at adapter init. In addition, these IQs don't need FL buffers since they only service indirect interrupts. One CIQ is setup per RX channel similar to the RDMA RXQs. iw_cxgb4 will utilize these CIQs based on the vector value passed into create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the number of CIQs configured, and thus the vector value will be the index into the array of CIQs.

2014-06-08i40e/i40evf: fix poll weightJesse Brandeburg
Fix a coding error where during the registration for NAPI the driver requested 256 budget. The max recommended value for this is NAPI_POLL_WEIGHT or 64.

2014-06-08i40e/i40evf: fix TSO accountingJesse Brandeburg
The TSO logic in the transmit path had some assumptions that have been broken now that the kernel can send as much as 32kB in a single skb->frag[.] entry, even on a system with 4kB pages. This fixes the assumptions and allows the kernel to operate as efficiently as possible with both SENDFILE and SEND. In addition, the hardware limit of data contained in a descriptor is changed to the next power of two below where it currently is in order to align to a power of two value, preventing a single byte of data in a descriptor.

2014-06-08i40e/i40evf: remove chatty reset messagesMitch Williams
Both the PF side and the VF side of the VF reset process are too noisy. We already warn the user that a reset is happening, and that is sufficient. Because some of these message are inside if statements, we have to rejigger the brackets at the same time to keep our coding style consistent.

2014-06-08i40e: not all VSIs have ringsMitch Williams
Once more, with feeling: not all VSIs have rings. To assume so is to invite null pointers to your party. Change-ID: I576858824468d9712d119fa1015a1f28c27712c4 Signed-off-by: Mitch Williams <mitch.a.williams@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

This patch fixes an issue where FD SB/ATR and NTUPLE configurations status are reported erroneously. Without this patch, driver reports FDir without further information.
