A VF should never be allowed to change the tuples for RSS for any PCTYPE since that's a global setting for the device in case of i40e devices.

| | | | | | | | | | | | | | | | If the driver calls skb_set_hash even with a zero hash, that indicates to the stack that the hash calculation is offloaded in hardware.

This patch fixes the path so that we do not call skb_set_hash if the feature is disabled.

* i40e: Look up MAC address in Open Firmware or IDPROMSowmini Varadhan2016-01-082-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC address in Open Firmware or IDPROM"). As with that fix, attempt to look up the MAC address in Open Firmware on systems that support it, and use IDPROM on SPARC if no OF address is found. In the case of the i40e there is an assumption that the default mac address has already been set up as the primary mac filter on probe, so if this filter is obtained from the Open Firmware or IDPROM, an explicit write is needed via i40e_aq_mac_address_write() and i40e_aq_add_macvlan() invocation. The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure tracks whether a platform-specific mac address was found, in which case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan() will be triggered.

* | sctp: Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRCTom Herbert2015-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The SCTP checksum is really a CRC and is very different from the standards 1's complement checksum that serves as the checksum for IP protocols. This offload interface is also very different. Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these differences. The term CSUM should be reserved in the stack to refer to the standard 1's complement IP checksum. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean the whole mac filter list when resetting after an intermediate add or delete push to the firmware. The code had evolved from using a list from the stack to a heap allocation, but the memset() didn't follow the change correctly. This now cleans the whole list rather that just part of the first element.

The overflow error in particular can happen when enabling a bunch of VFs and the VF driver is not blacklisted. Since these messages are really for debugging purposes, reclassify them as such.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When VFs are created, the MAC address defaults to all zeros, indicating to the VF driver that it should use a random MAC address. However, the PF driver was incorrectly adding this zero MAC to the filter table, along with the VF's randomly generated MAC address. Check for a good address before adding the default filter. While we're at it, make the error message a bit more useful.

To correct this, add a new function that unconditionally removes MAC addresses from all VLANs, and call this function when the VF requests a MAC filter removal.

Mitch updates the i40evf driver by increasing the maximum number of queues, since future devices will allow for more queue pairs. Cleans up a duplicate printing of the driver info string done in init, since it is already done in probe. Cleaned up the several allocations which did not need to be at atomic level, where GFP_KERNEL would work just fine. Then makes i40e_sync_vsi_filters() a more mature function, make having a common exit point so it will properly release the busy lock on the VSI and propagate errors to the callers. Then does some whitespace housekeeping in i40evf. Kiran moves and updates the detection/recovery of transmit queue hang code to service_task from tx_timeout function. Also fixed memory leak when users program flow-director filter using ethtool (sideband filter programming), the cause being the check of 'tx_buffer->skb' was preventing 'raw_buf' from being freed as part of the cleanup. Jesse enabled the ability to turn off/on packet split using ethtool priv flags. Then does some housekeeping for both the i40e and i40evf drivers which includes: remove unused/useless code, correct whitespace, remove duplicate #include, fix incorrect comment, etc... Neerav cleans up functions to gather Flow Control Rx XOFF stats, since the recent change in the driver logic for checking transmit hang has been moved, so these functions do not do anything meaningful any longer. ==================== Signed-off-by: David S.
