cnic,bnx2,bnx2x: use UIO_MEM_DMA_COHERENT Use the UIO_MEM_DMA_COHERENT type to properly handle mmap for dma_alloc_coherent buffers. The cnic l2_ring and l2_buf mmaps have caused page refcount issues as the dma_alloc_coherent no longer provide __GFP_COMP allocation as per commit "dma-mapping: reject __GFP_COMP in dma_alloc_attrs". Fix this by having the uio device use dma_mmap_coherent. The bnx2 and bnx2x status block allocations are also dma_alloc_coherent, and should use dma_mmap_coherent. They don't allocate multiple pages, but this interface does not work correctly with an iommu enabled unless dma_mmap_coherent is used.

cnic,bnx2i,bnx2fc: Fix inconsistent use of page size The bnx2/bnx2x rings are made up of linked pages. However there is an upper limit on the page size as some the page size settings are 16-bit in the hardware/firmware interface. In the current code, some parts use BNX2_PAGE_SIZE which has a 16K upper limit and some parts use PAGE_SIZE. On archs with >= 64K PAGE_SIZE, it generates some compile warnings. Define a new CNIC_PAGE_SZIE which has an upper limit of 16K and use it consistently in all relevant parts.

bnx2x, bnx2fc: Use per port max exchange resources The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices, or when working in multi-function mode, this resource needs to be distributed between the various possible FCoE functions. This information needs to be calculated by bnx2x and propagated into bnx2fc via cnic. bnx2fc can then use this value to calculate corresponding xid resources instead of using global constants.

cnic, bnx2x: Add CNIC_DRV_STATE_HANDLES_IRQ to ethdev->drv_state In INTA mode, cnic and bnx2x share the same IRQ. During chip reset, for example, cnic will stop servicing IRQs after it has shutdown the cnic hardware resources. However, the shared IRQ is still active as bnx2x needs to finish the reset. There is a window when bnx2x does not know that cnic is no longer handling IRQ and things don't always work properly. Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set before the first cnic IRQ is expected and cleared when no more cnic IRQs are expected, so there should be no race conditions.

bnx2x,cnic: use FW 7.8.2 This patch moves the bnx2x and cnic drivers into using FW 7.8.2 which was recently submitted into the linux-firmware tree. A short summary of minor bugs fixed by this FW: 1. In switch dependent mode, fix several issues regarding inner vlan vs. DCB priorities. 2. iSCSI - not all packets were completed on a forward channel. 3. DCB - fixed for 4-port devices. 4. Fixed false parity reported in CAM memories when operating near -5% on the 1.0V core supply. 5. ETS default settings are set to fairness between traffic classes (rather than strict priority), and uses the same chip receive buffer configuration for both PFC and pause. For a complete list of fixes made by this FW, see commit 236367db in the linux-firmware git repository.

cnic: Improve error recovery on bnx2x devices When a bnx2x device encounters parity errors, it will not respond to all SPQ messages. As a result, the shutdown sequence before reset can take a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout of all such messages. To improve this scenario, when bnx2x returns error on the SPQ, we'll send an immediate response to the ulp drivers to avoid such lengthy timeouts. Adjust the return code of relevant functions to return error only if the message cannot be sent on the SPQ so that we'll generate an error completion to the ulp drivers.
