2016-05-01i40e: Fix uninitialized variableCatherine Sullivan
We have an uninitialized variable warning for valid_len for one case in validate_vf_mesg. To fix this, just initialize it to 0 at the top of the function and remove all of the now redundant assignments to 0 in the individual cases.

2016-05-01i40e: Limit the number of MAC and VLAN addresses that can be added for VFsAnjali Singhai Jain
If the VF is privileged/trusted it can do as it may please including but not limited to hogging resources and playing unfair. But if the VF is not privileged/trusted it still can add some number (8) of MAC and VLAN addresses. Other restrictions with respect to Port VLAN and normal VLAN still apply to not privileged/trusted VF.

2016-04-26i40e/i40evf: Add support for IPIP and SIT offloadsAlexander Duyck

2016-04-26i40e/i40evf: Clean up feature flagsAlexander Duyck
The feature flags list for i40e and i40evf is beginning to become pretty massive. I plan to add another 4 or so features to these drivers and duplicating the flags for each and every flags list is becoming a bit repetitive. The primary change here is that we now build our features list around hw_encap_features. After that we assign that to vlan_features, hw_features, and finally map that onto features. In addition we end up throwing features onto hw_encap_features that end up having no effect such as the Rx offloads and SCTP_CRC. However that should have no impact and makes things a bit easier for us as hw_encap_features is one of the less updated features maps available. For i40evf I went through and sanity checked a few features as well. Specifically RXCSUM was being set as a read-only feature which didn't make much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag since that is really a software feature and not a hardware one anyway so disabling it is just a matter of ignoring the result from the hardware.

2016-04-13i40e/i40evf: Limit TSO to 7 descriptors for payload instead of 8 per packetAlexander Duyck
This patch addresses a bug introduced based on my interpretation of the XL710 datasheet. Specifically section 8.4.1 states that "A single transmit packet may span up to 8 buffers (up to 8 data descriptors per packet including both the header and payload buffers)." It then later goes on to say that each segment for a TSO obeys the previous rule, however it then refers to TSO header and the segment payload buffers. I believe the actual limit for fragments with TSO and a skbuff that has payload data in the header portion of the buffer is actually only 7 fragments as the skb->data portion counts as 2 buffers, one for the TSO header, and one for a segment payload buffer.

2016-04-05i40e: Notify VFs of all resetsMitch Williams
Notify VFs in the reset interrupt handler, instead of the actual reset initiation code. This allows the VFs to get properly notified for all resets, including resets initiated by different PFs on the same physical device.
