2016-07-14i40e: enable VSI broadcast promiscuous mode instead of adding broadcast filterKiran Patil
This patch sets VSI broadcast promiscuous mode during VSI add sequence and prevents adding MAC filter if specified MAC address is broadcast.

2016-07-14i40e/i40evf: Fix i40e_rx_checksumAlexander Duyck
There are a couple of issues I found in i40e_rx_checksum while doing some recent testing. As a result I have found the Rx checksum logic is pretty much broken and returning that the checksum is valid for tunnels in cases where it is not. First the inner types are not the correct values to use to test for if a tunnel is present or not. In addition the inner protocol types are not a bitmask as such performing an OR of the values doesn't make sense. I have instead changed the code so that the inner protocol types are used to determine if we report CHECKSUM_UNNECESSARY or not. For anything that does not end in UDP, TCP, or SCTP it doesn't make much sense to report a checksum offload since it won't contain a checksum anyway. This leaves us with the need to set the csum_level based on some value. For that purpose I am using the tunnel_type field. If the tunnel type is GRENAT or greater then this means we have a GRE or UDP tunnel with an inner header. In the case of GRE or UDP we will have a possible checksum present so for this reason it should be safe to set the csum_level to 1 to indicate that we are reporting the state of the inner header.

2016-06-27i40e: Don't notify client(s) for DCB changes on all VSIsNeerav Parikh
When LLDP/DCBX change happens the i40e driver code flow tried to notify the client(s) for each of the PF VSIs. This resulted into kernel panic on the first VSI that didn't have any netdev associated to it. The DCB change notification to the client(s) should be done only once for the PF/LAN VSI where the client(s) instances have been added to. Also, move the notification call after the PF driver has made changes related to the updated DCB configuration.

2016-06-27i40e: Fix RSS to not be limited by the number of CPUsCatherine Sullivan
Limiting qcount to pf->num_lan_msix, effectively limits the RSS queues to only use the number of CPUs, and ignore all other queues. We don't want to do this. If the user has changed the RSS settings to use more queues then CPUS, we want to trust they know what they are doing and let them. More importantly, if we tell them that is what we did, we want to actually do it and allow traffic into all of the queues we have allocated. This does not change the default setting to initially allocate only the number of CPUS of queue pairs.

previous patches removed all direct accesses to dev->trans_start, so change the netif_trans_update helper to update trans_start of netdev queue 0 instead and then remove trans_start from struct net_device. AFAICS a lot of the netif_trans_update() invocations are now useless because they occur in ndo_start_xmit and driver doesn't set LLTX (i.e. stack already took care of the update). As I can't test any of them it seems better to just leave them alone. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-01i40e/i40evf: Add support for GSO partial with UDP_TUNNEL_CSUM and GRE_CSUMAlexander Duyck
This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support segmentation for frames with checksums enabled in outer headers. As a result we can now send data over these types of tunnels at over 20Gb/s versus the 12Gb/s that was previously possible on my system. The advantage with the i40e parts is that this offload is mostly transparent as the hardware still deals with the inner and/or outer IPv4 headers so the IP ID is still incrementing for both when this offload is performed.

2016-05-01i40e/i40evf: fix I40E_MASK signed shift overflow warningsJacob Keller
GCC 6 has a new warning which will display when you attempt to left shift a signed value beyond the storage size of the type. I40E_MASK generates a mask value for 32bit registers. Properly typecast the mask value and place the values in parenthesis to prevent macro expansion issues.

2016-05-01i40e: Use consistent type for vf_idJesse Brandeburg
The driver was all over the place using signed or unsigned types for vf_id, when it should always be signed. This fixes warnings of type unsafe comparisons from gcc with W=2.

2016-05-01i40e: PTP - avoid aggregate return warningsJesse Brandeburg
Aggregate return warnings are when struct types are returned and must be copied to the lvalue with a struct copy by the compiler. This fixes warnings of type aggregate-return from gcc with W=2.
