* i40e: use valid online CPU on q_vector initializationGuilherme G. Piccoli2016-07-141-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the q_vector initialization routine sets the affinity_mask of a q_vector based on v_idx value. Meaning a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in SMT scenarios). If we disable some logical CPUs, by turning SMT off for example, we will end up with a sparse cpu_online_mask, i.e., only the first CPU in a core is online, and incremental filling in q_vector cpumask might lead to multiple offline CPUs being assigned to q_vectors. Example: if we have a system with 8 cores each one containing 8 logical CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is disabled, only the 1st CPU in each core remains online, so the cpu_online_mask in this case would have only 8 bits set, in a sparse way. In general case, when SMT is off the cpu_online_mask has only C bits set: 0, 1*N, 2*N, ..., C*(N-1) where C == # of cores; N == # of logical CPUs per core. In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set. This patch changes the way q_vector's affinity_mask is created: it iterates on v_idx, but consumes the CPU index from the cpu_online_mask instead of just using the v_idx incremental value. No functional changes were introduced.

* i40e/i40evf: Fix i40e_rx_checksumAlexander Duyck2016-07-141-13/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: define gso types for IPx over IPv4 and IPv6Tom Herbert2016-05-202-4/+2

These are used to described IP in IP tunnel and what the outer protocol is. The inner protocol can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.

* i40e: Limit the number of MAC and VLAN addresses that can be added for VFsAnjali Singhai Jain2016-05-012-2/+26
| | | | | | | | | | | | | | 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.

| | | | | | | | | | NFV use cases require the ability to steer packets to VSIs by VLAN tag alone while being in promiscuous mode for multicast and unicast MAC addresses. These two new functions support that ability.
