- wrap calls into cxgb3 and fail them if we're in the middle
of a PCI EEH event.
- correctly unwind and release endpoint and other resources when
we are in an EEH event.
- dispatch IB_EVENT_DEVICE_FATAL event when cxgb3 notifies iw_cxgb3 of
a fatal error.

The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3,
and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3
will load with firmware versions that iw_cxgb3 can't handle. The FW
major number indicates a specific interface between the FW and
iw_cxgb3. Thus if the major number of the running firmware does not
match the required version compiled into iw_cxgb3, then iw_cxgb3 must
not register that device.

cxgb3 does not currently report the page size capabilities, and
incorrectly reports them internally.
This version changes the bit-shifting to a static value (per Steve's
request).

Currently, iw_cxgb3 is severely limited on the amount of userspace
memory that can be registered in in a single memory region, which
causes big problems for applications that expect to be able to
register 100s of MB.
The problem is that the driver uses a single kmalloc()ed buffer to
hold the physical buffer list (PBL) for the entire memory region
during registration, which means that 8 bytes of contiguous memory are
required for each page of memory being registered. For example, a 64
MB registration will require 128 KB of contiguous memory with 4 KB
pages, and it unlikely that such an allocation will succeed on a busy
system.
This is purely a driver problem: the temporary page list buffer is not
needed by the hardware, so we can fix this by writing the PBL to the
hardware in page-sized chunks rather than all at once. We do this by
splitting the memory registration operation up into several steps:
- Allocate PBL space in adapter memory for the full registration
- Copy PBL to adapter memory in chunks
- Allocate STag and enable memory region
This also allows several other cleanups to the __cxio_tpt_op()
interface and related parts of the driver.
This change leaves the reregister memory region and memory window
operations broken, but they already didn't work due to other
longstanding bugs, so fixing them will be left to a later patch.

- Flush the QP only after the HW disables the connection. Currently
we flush the QP when transitioning to CLOSING. This exposes a race
condition where the HW can complete a RECV WR, for instance, -and-
the SW can flush that same WR.
- Only call CQ event handlers on flush IFF we actually flushed something.

cxgb3 only supports 4GB memory regions. The lustre RDMA code uses
this attribute and currently has to code around our bad setting.

- don't mark static functions in C files as inline - gcc should know
best whether inlining makes sense
- never compile the unused cxio_dbg.c
- make the following needlessly global functions static:
- cxio_hal.c: cxio_hal_clear_qp_ctx()
- iwch_provider.c: iwch_get_qp()
- remove the following unused global functions:
- cxio_hal.c: cxio_allocate_stag()
- cxio_resource.: cxio_hal_get_rhdl()
- cxio_resource.: cxio_hal_put_rhdl()
