* ixgbevf: add RSS support for X550Emil Tantilov2015-02-05
| | | | | | | | | | | X550 provides RSS registers for configuring RSS per VF. This patch introduces ixgbevf_setup_vfmrqc() which uses the VFRETA, VFRSSRK and VFMRQC registers to configure RSS on X550.

* fm10k: Validate VLAN ID in fm10k_update_xc_addr_pfMatthew Vick2015-02-05
| | | | | | | | | | | | Currently, fm10k_update_xc_addr_pf has an issue where it does not properly drop the upper-most four bits of the VLAN ID due to type promotion. Resolve the issue not by masking off the bits, but by throwing an error if the VLAN ID is out-of-bounds.

In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.

* | igb: Indicate failure on vf reset for empty mac addressAlexander Graf2015-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5ac6f91d changed the igb driver to expose a zero (empty) mac address to the VF on reset rather than a random one. However, that behavioral change also requires igbvf driver changes which can be hard especially when we want to talk to proprietary guest OSs. Looking at the code previous to the commit in Linux that made igbvf work with empty mac addresses (8d56b6d), we can see that on reset failure the driver will try to generate a new mac address with both the old and the new code. Furthermore, ixgbe does send reset failure when it detects an empty mac address (35055928c). So I think it's safe to make igb behave the same. With this patch I can successfully run a Windows 8.1 guest with an empty mac address and an assigned igbvf device that has no mac address set by the host. If anyone is aware of a guest driver that chokes on NACK returns of VF RESET commands, please speak up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.

* | e1000e: Fix 82572EI that has no hardware timestamp supportMathias Koehrer2015-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the Intel 82527EI (driver: e1000e) there is an issue when running the ptpd2 program, that leads to a kernel oops. The reason is here that in e1000_xmit_frame() a work queue will be scheduled that has not been initialized in this case. The work queue "tx_hwstamp_work" will only be initialized if adapter->flags & FLAG_HAS_HW_TIMESTAMP set. This check is missing in e1000_xmit_frame(). The following patch adds the missing check.

* | i40e: Support for NPAR iSCSI partition with DCBNeerav Parikh2015-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add parsing and reporting of iSCSI capability for a given device or function. Also add support for iSCSI partition type with DCB in NPAR mode. In this mode it is expected that software would configure both the LAN and iSCSI traffic classes for the iSCSI partition; whereas all the NIC type partitions will use LAN TC (TC0) only. Hence, the patch enables querying of DCB configuration in MFP mode and configures TCs for iSCSI partition type. Though NIC type partitions may not have more than 1 TC enabled for them the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED will be set/reset on all the partitions based on number of TCs on the port. This is required as in DCB environment it is expected that all traffic will be priority tagged.

| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of leaving the Rx timestamps in the same mode as before if we disable the Rx logic, we can set it into a mode that has the fewest possible timestamps generated. To do this, select only V1 mode, but do not enable UDP packet recognition. This should eliminate all (or at least almost all) Rx timestamps, since V1 packets are always over UDP.

| * i40e: adds FCoE configure optionVasu Dev2015-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds FCoE config option I40E_FCOE, so that FCoE can be enabled as needed but otherwise have it disabled by default. This also eliminate multiple FCoE config checks, instead now just one config check for CONFIG_I40E_FCOE. The I40E FCoE was added with 3.17 kernel and therefore this patch shall be applied to stable 3.17 kernel also.

| * i40e: Fix bug with TCP over IPv6 over VXLANAnjali Singhai2015-01-06
| | | | | | | | | | | | | | | | | | | | | | | | The driver was examining the outer protocol layer to set the inner protocol layer checksum offload. In the case of TCP over IPV6 over an IPv4 based VXLAN the inner checksum offloads would be set to look for IPv4/UDP instead of IPv6/TCP. This code fixes that so that the driver will look at the proper layer for encapsulation offload settings.

| * i40e: Fix Rx checksum error counterAnjali Singhai2015-01-06
| | | | | | | | | | | | | | | | | | | | | | The Rx port checksum error counter was incrementing incorrectly with UDP encapsulated tunneled traffic. This patch fixes the problem so that the port_rx_csum counter will show accurate statistics.

| * i40e: fix un-necessary Tx hangsJesse Brandeburg2015-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the driver was polling with interrupts disabled the hardware will occasionally not write back descriptors. This patch causes the driver to detect this situation and force an interrupt to fire which will flush the stuck descriptor. Does not conflict with napi because if we are already polling the napi_schedule is ignored. Additionally the extra interrupts are rate limited, so don't cause a burden to the CPU.

* | i40e: limit sriov to partition 1 of NPAR configurationsShannon Nelson2015-01-13
| | | | | | | | | | | | | | | | | | | | | | | | Make sure we only allow SR/IOV on the master PF of a port in multifunction mode. This should be the case anyway based on the num_vfs configured in the NVM, but this will help make sure there's no question. If we're not in multifunction mode the partition_id will always be 1.

| | | | | | | | | | | | | | | | | | | | | | Previously we were only checking if the link up state had changed, and if it hadn't exiting the link event routine early. We should also check if speed has changed, and if it has, stay and finish processing the link event.
