When initialising the CP0 status register during boot on 64-bit MIPS,
set all three of the kernel, supervisor, and user-mode 64-bit mode
flags. While FreeBSD does not currently use the supervisor ring (and
hence this is effectively a NOP on most systems), doing this avoids
triggering an exception on 64-bit MIPS CPUs that don't support 32-bit
compatibility mode, and therefore don't allow clearing the SX bit.

MFC r237049:
Pass flowid explicitly through the stack instead of taking it from
the mbuf chain at different places.
While there: Fix several bugs related to VRFs.
It turns out that too many drivers are not only parsing the L2/3/4
headers for TSO but also for generic checksum offloading. Ideally we
would only have one common function shared amongst all drivers, and
perhaps when updating them for IPv6 we should introduce that.
Eventually we should provide the meta information along with mbufs to
avoid (re-)parsing entirely.
To not break IPv6 (checksums and offload) and to be able to MFC the
changes without risking to hurt 3rd party drivers, duplicate the v4
framework, as other OSes have done as well.
Introduce interface capability flags for TX/RX checksum offload with
IPv6, to allow independent toggling (where possible). Add CSUM_*_IPV6
flags for UDP/TCP over IPv6, and reserve further for SCTP, and IPv6
fragmentation. Define CSUM_DELAY_DATA_IPV6 as we do for legacy IP and
add an alias for CSUM_DATA_VALID_IPV6.
This pretty much brings IPv6 handling in line with IPv4.
TSO is still handled in a different way and not via if_hwassist.
Update ifconfig to allow (un)setting of the new capability flags.
Update loopback to announce the new capabilities and if_hwassist flags.
Individual driver updates will have to follow, as will SCTP.
Removed the IFCAP_ prefix when printing the IPv6 checksum capabilities.
Factor out the tcp_hc_getmtu() call. As the comments say it
applies to both v4 and v6, so only write it once making it easier
to read the protocol family specifc code.
In case forwarding is turned on for a given address family, refuse to
queue the packet for LRO and tell the driver to directly pass it on.
This avoids re-assembly and later re-fragmentation problems when
forwarding.
It's not the best solution but the simplest and most effective for
the moment.
Make TCP LRO work properly with VIMAGE kernels rather than just panicing.
There's no VIMAGE context set there yet as this is before if_ethersubr.c.
Add code to handle pre-checked TCP checksums as indicated by mbuf
flags to save the entire computation for validation if not needed.
In the IPv6 TCP output path only compute the pseudo-header checksum,
set the checksum offset in the mbuf field along the appropriate flag
as done in IPv4.
In tcp_respond() just initialize the IPv6 payload length to 0 as
ip6_output() will properly set it.
Defer checksum calulations on UDP6 output and respect the mbuf
flags set by NICs having done checksum validation for us already,
thus saving the computing time in the input path as well.
Add support for delayed checksum calculations in the IPv6
output path. We currently cannot offload to the card if we
add extension headers (which incl. fragmentation).
Fix two SCTP offload support copy&paste bugs: calculate
checksums if fragmenting and no need to flag IPv4 header
checksums in the IPv6 forwarding path.
Correctly get the payload length in host byte order. While we
already plan to support >64k payload here, the IPv6 header payload
length obviously is only 16 bit and the calculations need to be right.
Hide the ip6aux functions. The only one referenced outside ip6_input.c
is not compiled in yet (__notyet__) in route6.c (r235954, r238231).
We do have accessor functions that should be used.
Significantly update tcp_lro for mostly two things:
1) introduce basic support for IPv6 without extension headers.
2) try hard to also get the incremental checksum updates right,
especially also in the IPv4 case for the IP and TCP header.
Move variables around for better locality, factor things out into
functions, allow checksum updates to be compiled out, ...
Leave a few comments on further things to look at in the future,
though that is not the full list.
Update drivers with appropriate #includes as needed for IPv6 data
type in LRO.
in_cksum.h required ip.h to be included for struct ip. To be
able to use some general checksum functions like in_addword()
in a non-IPv4 context, limit the (also exported to user space)
IPv4 specific functions to the times, when the ip.h header is
present and IPVERSION is defined (to 4).
Introduce a (for now copied stripped down) in6_cksum_pseudo()
function. We should be able to use this from in6_cksum() but
we should also ponder possible MD specific improvements.
It takes an extra csum argument to allow for easy checks as
will be done by the upper layer protocol input paths.
Optimize in6_cksum(), re-ordering work and limiting variable
initialization, removing a bzero() for mostly re-initialized
struct values, making use of the newly introduced in6_getscope(),
as well as converting an if/panic to a KASSERT().
Allow tso4 and tso6 be set individually given we have the bits.
This will help with drivers not working as expected during the
transition time and later.
Call set_terminal_mode() after video mode change, not before, because
video mode change always reset terminal mode to xterm.
It allows things like 'vidcontrol -T cons25 80x30' works as supposed,
and allows 'allscreens_flags="-T cons25 80x30"' in /etc/rc.conf too.
MFC r238022:

device names to shorten them. PulseAudio reported to have problems with

MFC r238011:
Restore GPIO config quirks handling, lost during last big refactoring.
This fixes sound from speakers on some laptops, including MacBook Pro.
Unfortunately the change in r237958 resulted in s/install/instclean/ due to
the aggressive pattern matching of the :C modifier. I tested build and
install in 2 phases, however with different solutions, resulting in the
breakage. Mea culpa.
The solution is to break out the all: target. This causes a few lines of
code duplication, but now the all: target works as it should, and the
other targets continue to work as they did before.
While I'm here, add a ===> header line to the start of each port build
to make it easier to find/more clear in the logs.

Switch back to the 4BSD scheduler for now. There is some more or less
recent regression with ULE, causing processes to get stuck in getblk
as well as interrupt handler execution delays to rise above the command
timeout of mpt(4).
Note that "HAVE_GETLINE" should be #undef'ed in config.h as were not using
the libc interface -- however that leads to redundant redeclaration compiler
warnings between the internal file.h and <stdio.h>.
MFC: r228193: tweak the r137233 fix to r136283 -- Code was making two send()
attempts vs. the comment documented "If we are working with a privileged
socket, then take only one attempt". Make the code match.
For the ports modules building code, clean WRKDIR before building. This is
important for those that use -DNO_CLEAN routinely, since it will prevent
installing stale stuff, and even more important when the port is upgraded
to a newer version. When the user doesn't use -DNO_CLEAN, this will create
an infinitesimal amount of extra work, but won't hurt anything.
This is necessary because the ports tree has flags that prevent the ususal
'update the build if newer source files exist' logic from doing what it
would do in the base.
MFC: r229809: Don't include <sys/timeb.h>.
The purpose of not including <sys/timeb.h> is to avoid the compiler
warning we put in <sys/timeb.h>. So this change will cause CVS to
provide its own definition of 'struct timeb'. This is only OK
because the code never calls the libc ftime(3) interface. CVS only
uses 'struct timeb' as a convenience structure -- thus it doesn't
matter how its supplied definition does or does not match the
ftime(3) ABI.
