This patch generalizes VXLAN forwarding table entries allowing an administrator to: 1) specify multiple destinations for a given MAC 2) specify alternate vni's in the VXLAN header 3) specify alternate destination UDP ports 4) use multicast MAC addresses as fdb lookup keys 5) specify multicast destinations 6) specify the outgoing interface for forwarded packets The combination allows configuration of more complex topologies using VXLAN encapsulation. Changes since v1: rebase to 3.9.0-rc2 Signed-Off-By:

caif_shm is an old implementation caif_shm will be replaced by caif_virtio [ As explained by Linus Walleij: "U5500 used this, but was cancelled and the silicon did not reach anyone outside ST-Ericsson. Then for the next platforms, we have gone for the leaner & cleaner approach of using virtio, rpmesg and rproc." ] Signed-off-by:

I believe these error messages are already logged on allocation failure by warn_alloc_failed and so get a dump_stack on OOM. Remove the unnecessary additional error logging. Around these deletions: o Alignment neatening. o Remove unnecessary casts of dma_alloc_coherent. o Hoist assigns from ifs. Signed-off-by:

The resource ID used for VM socket control packets (0) is already used for the VMCI_GET_CONTEXT_ID hypercall so a new ID (15) must be used when the guest sends these datagrams to the hypervisor. The hypervisor context ID must also be removed from the internal blacklist. Signed-off-by:

This patch allows LRO aggregation on bonded devices that contain an NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave) macro which executes for each slave that has bond as master. V3: After testing and discussing this with Rajesh, I decided to keep the vlan ip cache and just rename it to ip_cache since it will store bond ip addresses too. A new master flag has been added to the ip cache to denote that the address has been added because of a master device. I've taken care of the enslave/release cases by checking for various combinations of events and flags (e.g. netxen has a master, it's a bond master and it's not marked as a slave means it is being enslaved and is dev_open()ed in bond_enslave). I've changed netxen_free_ip_list() to have a "master" parameter which causes all IP addresses marked as master to be deleted (used when a netxen is being released). I've made the patch use the new upper device API as well. The following cases were tested: - bond -> netxen - vlan -> netxen - vlan -> bond -> netxen V2: Remove local ip caching, retrieve addresses dynamically and restore them if necessary. Note: Tested with NX3031 adapter. Tested-by:Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by:

This patch defines the common operations to support multiple chips. It includes common header file modifications to support the current chips (T4 and T5). It also includes the following bug fixes: - reconfirms the rnode state after an implicit logo. - corrects the stats array size. - sets up and checks flags correctly when coming up as master and finding the card initialized Reported-by:

T5 adapter does not support onchip queue memory. Present logic fails to allocate QP for T5 and returns an error. Also, if module parameter ocqp_support is zero then we are unable to allocate QP which should not be the case. Ideally if ocqp_support parameter is 0 or onchip queue support is disable then host QP should be allocated before returning an error. Signed-off-by:

It enables direct DMA by HW to memory region PBL arrays and fast register PBL arrays from host memory, vs the T4 way of passing these arrays in the WR itself. The result is lower latency for memory registration, and larger PBL array support for fast register operations. This patch also updates ULP_TX_MEM_WRITE command fields for T5. Ordering bit of ULP_TX_MEM_WRITE is at bit position 22 in T5 and at 23 in T4. Signed-off-by:

This patch implements a low latency Write Combining (aka Write Coalescing) work request path. PCIE maps User Space Doorbell BAR2 region writes to the new interface to SGE. SGE pulls a new message from PCIE new interface and if its a coalesced write work request then pushes it for processing. This patch copies coalesced work request to memory mapped BAR2 space.

When receiving a network coded packet, the decoding buffer is searched for a packet to use for decoding. The source, destination, and crc32 from the coded packet is used to identify the wanted packet. The decoded packet is passed to the usual unicast receiver function, as had it never been network coded. Signed-off-by:

To be able to decode a network coded packet, a node must already know one of the two coded packets. This is done by buffering skbs before transmission and buffering packets sniffed with promiscuous mode from other hosts. Packets are kept in a buffer similar to the one with forward-skbs: A hash table, where each entry, which corresponds to a src-dst pair, has a linked list packets. Signed-off-by:

Before adding forward-skbs to the coding buffer, the buffer is searched for a potential coding opportunity. If one is found, the two packets are network coded and transmitted right away. If not, the forward-skb is added to the buffer. Network coded packets are transmitted with information about the two receivers and the two coded packets. The first receiver is given by the MAC header, while the second is given in the payload/bat-header. The second receiver uses promiscuous mode to receive the packet and check the second destination.

Two be able to network code two packets, one packet must be buffered until the next is available. This is done in a "coding buffer", which is essentially a hash table with lists of packets. Each entry in the hash table corresponds to a specific src-dst pair, which has a linked list of packets that are buffered. This patch adds skbs to the buffer just before forwarding them. The buffer is traversed every 10 ms, where timed skbs are removed from the buffer and transmitted. To allow experiments with the network coding scheme, the timeout is tunable through a file in debugfs. Signed-off-by:

To use network coding efficiently, a relay must know when neighbor nodes are likely to have enough information to be able to decode a network coded packet. This is detected by using OGMs from batman-adv to discover when one neighbor is in range of another neighbor. The relay check the TLL to detect when an OGM is forwarded from one neighbor by another neighbor, and thereby knows that the two neighbors are in range and thus overhear packets sent by each other. This information is saved in the orig_node struct to be used when searching for coding opportunities. Two lists are added to the orig_node struct: One for neighbors that can hear the orig_node (outgoing nc_nodes) and one for neighbors that the orig_node can hear (incoming nc_nodes). Information about nc_nodes is kept for 10 seconds and is available through debugfs in batman_adv/nc_nodes to use when debugging network coding. Signed-off-by:
