2017-10-19qed: Fix iWARP out of order flowMichal Kalderon1-0/+1
Out of order flow is not working for iWARP. This patch got cut out from initial series that added out of order support for iWARP. Make out of order code common for iWARP and iSCSI. Add new configuration option CONFIG_QED_OOO. Set by qedr and qedi Kconfigs.

2017-08-10RDMA: Simplify get firmware interfaceLeon Romanovsky1-3/+2
There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature. Signed-off-by: Leon Romanovsky <leonro@mellanox.com>

2017-06-09qed*: LL2 callback operationsMichal Kalderon3-58/+188
LL2 today is interrupt driven - when tx/rx completion arrives [or any other indication], qed needs to operate on the connection and pass the information to the protocol-driver [or internal qed consumer]. Since we have several flavors of ll2 employeed by the driver, each handler needs to do an if-else to determine the right functionality to use based on the connection type. In order to make things more scalable [given that we're going to add additional types of ll2 flavors] move the infrastrucutre into using a callback-based approach - the callbacks would be provided as part of the connection's initialization parameters.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma DMA mapping updates from Doug Ledford: "Drop IB DMA mapping code and use core DMA code instead. Bart Van Assche noted that the ib DMA mapping code was significantly similar enough to the core DMA mapping code that with a few changes it was possible to remove the IB DMA mapping code entirely and switch the RDMA stack to use the core DMA mapping code. This resulted in a nice set of cleanups, but touched the entire tree and has been kept separate for that reason." * tag 'for-next-dma_ops' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (37 commits) IB/rxe, IB/rdmavt: Use dma_virt_ops instead of duplicating it IB/core: Remove ib_device.dma_device nvme-rdma: Switch from dma_device to dev.parent RDS: net: Switch from dma_device to dev.parent IB/srpt: Modify a debug statement IB/srp: Switch from dma_device to dev.parent IB/iser: Switch from dma_device to dev.parent IB/IPoIB: Switch from dma_device to dev.parent IB/rxe: Switch from dma_device to dev.parent IB/vmw_pvrdma: Switch from dma_device to dev.parent IB/usnic: Switch from dma_device to dev.parent IB/qib: Switch from dma_device to dev.parent IB/qedr: Switch from dma_device to dev.parent IB/ocrdma: Switch from dma_device to dev.parent IB/nes: Remove a superfluous assignment statement IB/mthca: Switch from dma_device to dev.parent IB/mlx5: Switch from dma_device to dev.parent IB/mlx4: Switch from dma_device to dev.parent IB/i40iw: Remove a superfluous assignment statement IB/hns: Switch from dma_device to dev.parent ...

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull Mellanox rdma updates from Doug Ledford: "Mellanox specific updates for 4.11 merge window Because the Mellanox code required being based on a net-next tree, I keept it separate from the remainder of the RDMA stack submission that is based on 4.10-rc3. This branch contains: - Various mlx4 and mlx5 fixes and minor changes - Support for adding a tag match rule to flow specs - Support for cvlan offload operation for raw ethernet QPs - A change to the core IB code to recognize raw eth capabilities and enumerate them (touches non-Mellanox code) - Implicit On-Demand Paging memory registration support" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (40 commits) IB/mlx5: Fix configuration of port capabilities IB/mlx4: Take source GID by index from HW GID table IB/mlx5: Fix blue flame buffer size calculation IB/mlx4: Remove unused variable from function declaration IB: Query ports via the core instead of direct into the driver IB: Add protocol for USNIC IB/mlx4: Support raw packet protocol IB/mlx5: Support raw packet protocol IB/core: Add raw packet protocol IB/mlx5: Add implicit MR support IB/mlx5: Expose MR cache for mlx5_ib IB/mlx5: Add null_mkey access IB/umem: Indicate that process is being terminated IB/umem: Update on demand page (ODP) support IB/core: Add implicit MR flag IB/mlx5: Support creation of a WQ with scatter FCS offload IB/mlx5: Enable QP creation with cvlan offload IB/mlx5: Enable WQ creation and modification with cvlan offload IB/mlx5: Expose vlan offloads capabilities IB/uverbs: Enable QP creation with cvlan offload ...
