Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

To allow allocating an aligned range of consecutive QP numbers, add an interface to reserve an aligned range of QP numbers and have the QP allocation function always take a QP number. This will be used for RSS support in the mlx4_en Ethernet driver and also potentially by IPoIB RSS support.

MTT entries are allocated with a buddy allocator, which just keeps bitmaps for each level of the buddy table. However, all free space starts out at the highest order, and small allocations start scanning from the lowest order. When the lowest order tables have no free space, this can lead to scanning potentially millions of bits before finding a free entry at a higher order. We can avoid this by just keeping a count of how many free entries each order has, and skipping the bitmap scan when an order is completely empty. This provides a nice performance boost for a negligible increase in memory usage. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

In addition to mlx4_ib, there will be ethernet and FC consumers of mlx4_core, so move the code for managing kernel doorbells into the core module to avoid having to duplicate this multiple times.

The struct mlx4_interface.event() method was supposed to get an enum mlx4_dev_event, but the driver code was actually passing in the hardware enum mlx4_event values. Fix up the callers of mlx4_dispatch_event() so that they pass in the right type of value, and fix up the event method in mlx4_ib so that it can handle the enum mlx4_dev_event values. This eliminates the need for the subtype parameter to the event method, so remove it. This also fixes the sparse warning drivers/net/mlx4/intf.c:127:48: warning: mixing different enum types drivers/net/mlx4/intf.c:127:48: int enum mlx4_event versus drivers/net/mlx4/intf.c:127:48: int enum mlx4_dev_event Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Increase the number of QPs allowed per multicast group from 8 to 56. This allows for one QP per core on 16-core systems, which are now quite common, and allows some space for future growth. Signed-off-by: NJack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Enable having ICM tables in coherent memory, and use coherent memory for the dMPT table. This will allow writing MPT entries for MRs both via the SW2HW_MPT command and also directly by the driver for FMR remapping without needing to flush or worry about cacheline boundaries.

Reset the device when an internal error is detected. Also, detect errors by polling the error buffer rather than using interrupts. This is more robust and doesn't depend on MSI-X. Remove the old interrupt handler entirely, since we don't want to support two mechanisms for detecting internal errors.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
