update to the latest internal shared code.
- Add a chip_params structure to keep track of hardware constants for
all generations of Terminators handled by cxgbe.
- Update t4_hw_pci_read_cfg4 to work with T6.
- Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to
work with T6. Most of the changes are in the decoders for the CIM
logic analyzer and the MPS TCAM.
- Acquire the regwin lock around indirect register accesses.

Each channel contains one RX ring and one TX ring. And we
try to distribute the channels to different evenly.
Note: Currently we don't have enough information to extract
the RSS type and RSS hash value from the received packets.
This greatly improves the TX/RX performance for 8 virtual CPU
Hyper-V over 10Ge: it can max out 10Ge for TCP when multiple
RX/TX rings are enabled.
This almost doubles the TX/RX performance for locally connected
Hyper-Vs: was 6Gbps w/ 128 TCP streams, now 11Gbps w/ multiple
RX/TX rings enabled.
It is not enabled by default; it will be switched on after more
tests.

Currently the base.txz distribution does not get the BSD.debug.dist mtree
extracted into it. So if you start from that and then try to build a 3rd-party
application outside of buildworld it will by-default try installing the
debug files into a missing directory if they are being installed into /usr/lib.
Check for the existence before forcing the directory to be created rather than
the older way of running a shell command with test -d || mkdir -p always.

Summary:
The idea behind this is '~0ul' is well-defined, and casting to uintmax_t, on a
32-bit platform, will leave the upper 32 bits as 0. The maximum range of a
resource is 0xFFF.... (all bits of the full type set). By dropping the 'ul'
suffix, C type promotion rules apply, and the sign extension of ~0 on 32 bit
platforms gets it to a type-independent 'unsigned max'.

This was a regression in r295985.
bsd.dep.mk adds to SRCS for dtrace probes, yacc grammars and some
others.
The code that is moving is planned to be removed once FAST_DEPEND is
default (and the only option) though since FAST_DEPEND doesn't use this.

but next invocation is cancelled while migrating,
sleepq_check_timeout() needs to be informed that the callout is
stopped. Otherwise the thread switches off CPU and never become
runnable, since running callout could have already raced with us,
while the migrating and cancelled callout could be one which is
expected to set TDP_TIMOFAIL flag for us. This contradicts with the
expected behaviour of callout_stop() for other callers, which
e.g. decrement references from the callout callbacks.
Add a new flag CS_MIGRBLOCK requesting report of the situation as
'successfully stopped'.

dynamic linker must be prepared to handle relocations against any

For each read-only segment, add write permission before relocs are
processed, and return to the mapping mode requested by the phdr, after

Things changed:
* do not allocate 4GB of SLI space, because it's the waste of
system resources. Allocate only small portions when needed.
* provide own implementation of activate_resource which performs
address translation between PCI bus and host PA address space.
This is temporary solution, should be replaced by bus_map_resource
