Ordinary input to this macro comes from pe_code, which is uint16_t. Coverity
points out that shifting such a value discards the result of a 24 bit shift,
which is not what we want.

When a "pnfs" NFSv4.1 mount is hung because of an unresponsive DS,
a forced dismount wouldn't work, because the RPC socket for the DS
was not being closed. This patch fixes this.
This will only affect "pnfs" mounts where the pNFS server's DS
is unresponsive (crashed or network partitioned or...).
Found during testing of the pNFS server.

Add sanity checks in ql_hw_send() qla_send() to ensure that empty slots
in Tx Ring map to empty slot in Tx_buf array before Transmits. If the
checks fail further Transmission on that Tx Ring is prevented.
From ACPICA 20170929, AcpiOsGetTimer() should be available early because
While() loop timeout mechanism was reimplemented with it. Unfortunately,
it means AcpiLoadTables() may cause panic when a While() loop is executed.
After having lengthy discussions with ACPICA developers, I have concluded
that dummy timecounter is good enough for the purpose and it is the least
intrusive solution for now. Also, they reminded me the ACPI specification
implies OS timer function should be available before loading tables.
this is more friendly to the tree.
Tested this with loader.conf:if_igb_load="YES" and it does the right
thing.

Background:
- UDP 4-tuple hash type is unconditionally enabled in Hyper-V on WS2016,
which is _not_ affected by NDIS_OBJTYPE_RSS_PARAMS.
- Non-fragment UDP/IPv4 datagrams' hash type is delivered to VM as
TCP_IPV4.
Currently this erroneous behavior only applies to WS2016/Windows10.
Force l3/l4 protocol check, if the RXed packet's hash type is TCP_IPV4,
and the Hyper-V is running on WS2016/Windows10. If the RXed packet is
UDP datagram, adjust mbuf hash type to UDP_IPV4.

^/head@r323923 changed when MODIFIED is printed at exit. It's better to follow the
documented way of determining whether or not a filesystem is clean per fsck_ffs, i.e.,
ensure that the exit code is either 0 or 7.
The pass/fail determination is brittle prior to this commit, and ^/head@r323923 made
the issue apparent -- thus this needs to be fixed independent of ^/head@r323923.

o Fall back to default m_ext free mech, using function pointer in
m_ext_free, and remove sf_ext_free() called directly from mbuf code.
Testing on modern CPUs showed no regression.
o Provide internally used flag EXT_FLAG_SYNC, to mark that I/O uses
SF_SYNC flag. Lack of the flag allows us not to dereference
ext_arg2, saving from a cache line miss.
o Create function sendfile_free_page() that later will be used, for
multi-page mbufs. For now compiler will inline it into
sendfile_free_mext().

However, treat EXT_EXTREF mbufs differently, since they are different -
they don't have a refcount holding mbuf.

and change from r296242.
