Normally this routine is supposed to loop until the PIC returns a "no more
interrupts pending" indication. I had commented that out to do just one
interrupt per invokation to do some timing tests.

- Remove redundant NBLONG macro and use BIT_WORD()
and BIT_MASK() instead.
- Correctly define BIT_MASK() according to Linux and
update all users of this macro.
- Add missing GENMASK() macro.
- Remove all comments deriving from Linux.

Benchmarking showed a significant performance increase with the MTU size
to 64k instead of 16k. Change the driver default to 64k.

Throw away the result of the peer SPAD read. The peer will write our
local SPAD and we need to keep the locally read SPAD value to check if
the remote side is up.

Reset the link stats when the link goes down. In particular, the TX and
RX index and count must be reset, or else the TX side will be sending
packets to the RX side where the RX side is not expecting them. Reset
all the stats, to be consistent.

We skip actually bringing up Rootport/Transparent configurations, so
most of this doesn't apply. Original Linux commit log:
Link training should be enabled in the driver probe for root port mode.
We should not have to wait for transport to be loaded for this to
happen. Otherwise the ntb device will not show up on the transparent
bridge side of the link.

The bits in the aux control register vary based on the processor type. In
the past we've always just set the 'smp' and "broadcast tlb/cache ops' bits,
which worked fine for the first few SoCs we supported. Now that we support
most of the cortex-a series processors, it's important to get the right bits
set based on the processor type.

It is just a trivial wrapper around ntb_mw_set_trans().

The failure path for allocating rx grant refs should not try to free tx
grant refs because tx grant refs were allocated after that. Also fix the
error path for xen_net_read_mac.

Multiqueue feature will make the number of queues dynamic, so XN_LOCK_INIT
won't be that useful. Remove the macro and call mtx_init directly.
XN_LOCK_DESTROY is just dead code.

Currently neither Linux nor FreeBSD netback supports page flipping. NetBSD
still supports that. It is not sure how many people actually use page
flipping, but page flipping is supposed to be slower than copying nowadays.
It will also shatter frontend / backend address space.
Overall this feature is more of a burden than a benefit.
