The rcd array can be accessed from user context or during interrupts.
Protecting this with a mutex isn't a good idea because the mutex should
not be used from an IRQ.
Protect the allocation and freeing of rcd array elements with a
spinlock.

When DC is shut down (by e.g. disconnecting the cable), the
driver should use host_link_state to get port's current
physical state. This is due to the fact that physical state
is read from DC's CSRs and when DC is shut down and state is
changed, its registers are not impacted.

ETHTOOL_FWVERS_LEN, because many drivers anyway are limited

When an egress resource(SDMA descriptors, pio credits) is not available,
a sending thread will be put on the resource's wait queue. When the
resource becomes available again, up to a fixed number of sending threads
can be awakened sequentially and removed from the wait queue, depending
on the number of waiting threads and the number of free resources. Since
each awakened sending thread will send as many packets as possible, it
is highly likely that the first sending thread will consume all the
egress resources. Subsequently, it will be put back to the end of the wait
queue. Depending on the timing when the later sending threads wake up,
they may not be able to send any packet and be again put back to the end
of the wait queue sequentially, right behind the first sending thread.
This starvation cycle continues until some sending threads exceed their
retry limit and consequently fail.
This patch fixes the issue by two simple approaches:
(1) Any starved sending thread will be put to the head of the wait queue
while a served sending thread will be put to the tail;
(2) The most starved sending thread will be served first.

[ 1884.818167] hfi1 0000:05:00.0: hfi1_0: WC Remapped RcvArray:
ffffc9000a980000
The ioremap_wc() clearly is not returning a write combining mapping due
to an overlap where the RcvArray is mapped in a uncached mapping prior
to creating the proposed write combining mapping.
The patch replaces the single base register for uncached CSRs that
used to overlap the RcvArray with two mappings. One, kregbase1, from the
bar0 up to the RcvArray and another, kregbase2, from the end of the
RcvArray to the pio send buffer space. A new dd field, base2_start,
is used to convert the zero-based offset in the CSR routines to the
correct kregbase1/kregbase2 mapping. A single direct write of the
RcvArray CSRs is replaced with hfi1_put_tid() to insure correct access
using the new disjoint mapping.
Additionally, the kregend field is deleted since it is only ever written.
patdebug now shows the RcvArray as write combining:
[ 35.688990] x86/PAT: reserve_memtype added [mem 0x91200000-0x9127ffff],
track write-combining, req write-combining, ret write-combining
To insulate from any potential issues with write combining, all
writeq are now flushed in hfi1_put_tid() and rcv_array_wc_fill().

Base receive contexts can be used by sub contexts. Because of this,
resources for the context cannot be completely freed until all sub

Introduce a reference count so that the base receive context can be
freed only when all sub contexts are done with it.
Use the provided function call for setting default send context
integrity rather than the manual method.
The cleanup path does not set all variables back to NULL after freeing
resources. Since the clean up code can get called more than once,
(e.g. during context close and on the error path), it is necessary to
make sure that all the variables are NULLed.
