mana: some code refactoring and export apis for future RDMA driver - Record the physical address for doorbell page region For supporting RDMA device with multiple user contexts with their individual doorbell pages, record the start address of doorbell page region for use by the RDMA driver to allocate user context doorbell IDs. - Handle vport sharing between devices For outgoing packets, the PF requires the VF to configure the vport with corresponding protection domain and doorbell ID for the kernel or user context. The vport can't be shared between different contexts. Implement the logic to exclusively take over the vport by either the Ethernet device or RDMA device. - Add functions for allocating doorbell page from GDMA The RDMA device needs to allocate doorbell pages for each user context. Implement those functions and expose them for use by the RDMA driver. - Export Work Queue functions for use by RDMA driver RDMA device may need to create Ethernet device queues for use by Queue Pair type RAW. This allows a user-mode context accesses Ethernet hardware queues. Export the supporting functions for use by the RDMA driver. - Define max values for SGL entries The number of maximum SGl entries should be computed from the maximum WQE size for the intended queue type and the corresponding OOB data size. This guarantees the hardware queue can successfully queue requests up to the queue depth exposed to the upper layer. - Define and process GDMA response code GDMA_STATUS_MORE_ENTRIES When doing memory registration, the PF may respond with GDMA_STATUS_MORE_ENTRIES to indicate a follow request is needed. This is not an error and should be processed as expected. - Define data structures for protection domain and memory registration The MANA hardware support protection domain and memory registration for use in RDMA environment. Add those definitions and expose them for use by the RDMA driver. MFC after: 2 weeks Sponsored by: Microsoft

mana: fix misc minor handlding issues when error happens. - In mana_create_txq(), if test fails we must free some resources as in all the other handling paths of this function. - In mana_gd_read_cqe(), add warning log in case of CQE read overflow, instead of failing silently. - Fix error handling in mana_create_rxq() when cq->gdma_id >= gc->max_num_cqs. - In mana_init_port(), use the correct port index rather than 0. - In mana_hwc_create_wq(), If allocating the DMA buffer fails, mana_hwc_destroy_wq was called without previously storing the pointer to the queue. In order to avoid leaking the pointer to the queue, store it as soon as it is allocated. MFC after: 2 weeks Sponsored by: Microsoft

mana: Improve the HWC error handling Currently when the HWC creation fails, the error handling is flawed, e.g. if mana_hwc_create_channel() -> mana_hwc_establish_channel() fails, the resources acquired in mana_hwc_init_queues() is not released. Enhance mana_hwc_destroy_channel() to do the proper cleanup work and call it accordingly. MFC after: 2 weeks Sponsored by: Microsoft

Mana: move mana polling from EQ to CQ -Each CQ start task queue to poll when completion happens. This means every rx and tx queue has its own cleanup task thread to poll the completion. - Arm EQ everytime no matter it is mana or hwc. CQ arming depends on the budget. - Fix a warning in mana_poll_tx_cq() when cqe_read is 0. - Move cqe_poll from EQ to CQ struct. - Support EQ sharing up to 8 vPorts. - Ease linkdown message from mana_info to mana_dbg.

Microsoft Azure Network Adapter(MANA) VF support MANA is the new network adapter from Microsoft which will be available in Azure public cloud. It provides SRIOV NIC as virtual function to guest OS running on Hyper-V. The code can be divided into two major parts. Gdma_main.c is the one to bring up the hardware board and drives all underlying hardware queue infrastructure. Mana_en.c contains all main ethernet driver code. It has only tested and supported on amd64 architecture.
