Adding bridge support to the batman-adv multicast optimization requires batman-adv knowing about the existence of bridged-in IGMP/MLD queriers to be able to reliably serve any multicast listener behind this same bridge. Signed-off-by:

With this new, exported function br_multicast_list_adjacent(net_dev) a list of IPv4/6 addresses is returned. This list contains all multicast addresses sensed by the bridge multicast snooping feature on all bridge ports of the bridge interface of net_dev, excluding addresses from the specified net_device itself. Adding bridge support to the batman-adv multicast optimization requires batman-adv knowing about the existence of bridged-in multicast listeners to be able to reliably serve them with multicast packets.

MLDv1 (RFC2710 section 6), MLDv2 (RFC3810 section 7.6.2), IGMPv2 (RFC2236 section 3) and IGMPv3 (RFC3376 section 6.6.2) specify that the querier with lowest source address shall become the selected querier. So far the bridge stopped its querier as soon as it heard another querier regardless of its source address. This results in the "wrong" querier potentially becoming the active querier or a potential, unnecessary querying delay. With this patch the bridge memorizes the source address of the currently selected querier and ignores queries from queriers with a higher source address than the currently selected one. This slight optimization is supposed to make it more RFC compliant (but is rather uncritical and therefore probably not necessary to be queued for stable kernels). Signed-off-by:

The current naming of these two structs is very random, in that reversing their naming would not make any semantical difference. This patch tries to make the naming less confusing by giving them a more specific, distinguishable naming. This is also useful for the upcoming patches reintroducing the "struct bridge_mcast_querier" but for storing information about the selected querier (no matter if our own or a foreign querier).

Select the appropriate hw mtu index and initial sequence number to optimize hw memory performance. Add new cxgb4_best_aligned_mtu() which allows callers to provide enough information to be used to [possibly] select an MTU which will result in the TCP Data Segment Size (AKA Maximum Segment Size) to be an aligned value. If an RTR message exhange is required, then align the ISS to 8B - 1 + 4, so that after the SYN the send seqno will align on a 4B boundary. The RTR message exchange will leave the send seqno aligned on an 8B boundary. If an RTR is not required, then align the ISS to 8B - 1. The goal is to have the send seqno be 8B aligned when we send the first FPDU. Based on original work by Casey Leedom <leeedom@chelsio.com> and Steve Wise <swise@opengridcomputing.com> Signed-off-by:

Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA RXQs, which also handle direct interrupts for offload CPLs during RDMA connection setup/teardown. The intended T4 usage model, however, is to have indirect interrupts flow through dedicated IQs. IE not to mix indirect interrupts with CPL messages in an IQ. This patch adds the concept of RDMA concentrator IQs, or CIQs, setup and maintained by the LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will flow through the LLD's RDMA RXQs, and CQ interrupts flow through the CIQs. Design: cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs are sized according to the max available CQs available at adapter init. In addition, these IQs don't need FL buffers since they only service indirect interrupts. One CIQ is setup per RX channel similar to the RDMA RXQs. iw_cxgb4 will utilize these CIQs based on the vector value passed into create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the number of CIQs configured, and thus the vector value will be the index into the array of CIQs.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-09 This series contains more updates to i40e and i40evf. Shannon adds checks for error status bits on the admin event queue and provides notification if seen. Cleans up unused variable and memory allocation which was used earlier in driver development and is no longer needed. Also fixes the driver to not complain about removing non-existent MAC addresses. Bumps the driver versions for both i40e and i40evf. Catherine fixes a function header comment to make sure the comment correctly reflects the function name. Mitch adds code to allow for additional VSIs since the number of VSIs that the firmware reports to us is a guaranteed minimum, not an absolute maximum. The hardware actually supports for more than the reported value, which we often need. Implements anti-spoofing for VFs for both MAC addresses and VLANs, as well as enable this feature by default for all VFs. Anjali changes the interrupt distribution policy to change the way resources for special features are handled. Fixes the driver to not fall back to one queue if the only feature enabled is ATR, since FD_SB and FD_ATR need to be checked independently in order to decide if we will support multiple queue or not. Allows the RSS table entry range and GPS to be any number, not necessarily a power of 2 because hardware does not restrict us to use a power of 2 GPS in the case of RSS as long as we are not sharing the RSS table with another VSI (VMDq). Frank modifies the driver to keep SR-IOV enabled in the case that RSS, VMFq, FD_SB and DCB are disabled so that SR-IOV does not get turned off unnecessarily. Jesse fixes a bug in receive checksum where the driver was not marking packets with bad checksums correctly, especially IPv6 packets with a bad checksum. To do this correctly, we need a define that may be set by hardware in rare cases. Greg fixes the driver to delete all the old and stale MAC filters for the VF VSI when the host administrator changes the VF MAC address from under its feet. ==================== Signed-off-by:

We tell the HW upper boundary of power of 2 in VSI config, but the HW does not restrict us to use just power of 2 GPS in case of RSS as long as we are not sharing the RSS table with another VSI (VMDq). We at present are not doing RSS in VMDq VSI. If we were to enable that and if the system had CPU count which was not power 2, the VMDq VSIs will see a little skewed distribution.

The number of VSIs that the firmware reports to us is a guaranteed minimum, not an absolute maximum. The hardware actually supports far more than the reported value, which we often need. To allow for this, we allocate space for a larger number of VSIs than is guaranteed by the firmware, with the knowledge that we may fail to get them all in the future. Note that we are just allocating pointers here, the actual (much larger) VSI structures are allocated on demand. Change-ID: I6f4e535ce39d3bf417aef78306e04fbc7505140e Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-08 This series contains updates to i40e and i40evf. Jesse fixes an issue reported by Eric Dumazet where the driver was not masking the right bits in the receive descriptor before checking them. Also fixes TSO accounting since the kernel now can send as much as 32kB in a single skb->frag[.] entry, even on a system with 4kB pages. Anjali cleans up registers which are no longer supported. Akeem cleans up code comments and removes num_msix_entries from the interrupt setup routine since it was not being used. Fixes an issue where FD SB/ATR and NTUPLE configuration status were reported erroneously, so now the driver reports FDir without further information. Fixes a coding error where during the registration for NAPI, the driver was requesting 256 budget. The max recommended value for this NAPI_POLL_WEIGHT or 64. Lastly, removed deprecated device IDs because they will not be shipped. Mitch removes log messages which were redundant so therefore unnecessary. Also removes a bogus code comment since VF drivers require MSI-X or they won't get interrupts at all and cleans up the formatting of several log messages. Mitch also fixes the possibility of null pointers in VSI, since not all VSIs have transmit rings. Shannon ensures to clear the PXE mode bit on each reset after the AdminQ has been rebuilt. Catherine bumps the driver versions for i40e and i40evf. ==================== Signed-off-by:

The TSO logic in the transmit path had some assumptions that have been broken now that the kernel can send as much as 32kB in a single skb->frag[.] entry, even on a system with 4kB pages. This fixes the assumptions and allows the kernel to operate as efficiently as possible with both SENDFILE and SEND. In addition, the hardware limit of data contained in a descriptor is changed to the next power of two below where it currently is in order to align to a power of two value, preventing a single byte of data in a descriptor.

Both the PF side and the VF side of the VF reset process are too noisy. We already warn the user that a reset is happening, and that is sufficient. Because some of these message are inside if statements, we have to rejigger the brackets at the same time to keep our coding style consistent.
