Fix difftime() result when it is passed a negative value
We need to cast the result of bitwise AND to time_t before the cast
to double in the HI and LO macros. Otherwise, we get a very large
positive floating point value instead of a negative value.

pf_purge_states() may trip assert(st->timeout == PFTM_UNLINKED)
in pf_free_state(). Once member ->timeout in pf_state structure
reaches PFTM_UNLINKED value, then the ->timeout member must not
not be updated. This diff reminds pfsync(4) to follow PFTM_UNLINKED
rule too. The pfsync(4) currently may accidentally update ->timeout
member while state is being purged, causing pf_purge_states() to
trip the assert.
Issue was kindly reported by Stuart Henderson.

fix tx dma segment size
i thought it was weird that an MI driver like ix(4) is using an MD
number like PAGE_SIZE for the maximum segment size in its tx dma
maps. the manual says tx segments can be 16k (and goes into a 16bit
field), so let's try using the documented value here.
the rx descs also use 16 * 1024 as a magic number here, so it's in
keeping with other code in the same driver.
tested by me on arm64 and sparc64 (which has 8k pages)

fix rss hashing on big endian archs
i noticed that packets seem to be hashed differently by the network
stack and this hardware on sparc64. mucking around with how we
handle the endianness of the rss key programmed via registers makes
it consistent on both big and little archs.

increase the 9k mbuf clusters to 9k + 128 bytes
pools try to amortise the cost of items against the underlying
kernel memory allocator by rounding the "page" size up to fit at
least 8 items, and then rounding that up to the next power of 2.
the 9k clusters are 9 * 1024 bytes, which is 72k after being
multiplied by 8, which becomes 128k cos it's the next power of 2.
if you divide 128k by 9k, you get 14 and some change. there's enough
change that we can raise the cluster size by 128 bytes without
affecting the page size or the number of items on the page. ie,
it's still going to use 128k "pages" and fit 14 clusters.
i can take advantage of this in some drivers for stupid hardware,
so given the above it seems like a plan without any drawbacks apart
from the pool name getting a bit bigger.

sys/cnmac: support CN71xx 1000BASE-X ports
Some CN71xx boards describe active GMX ports only in the PIP device
tree, and mark the CPU facing link as cavium,sgmii-mac-1000x-mode with
cavium,disable-autonegotiation, but without a PHY handle. OpenBSD
otherwise trusts GMX0_INF_MODE for port discovery and insists on a PHY
attach in cn30xxgmx_attach(), so such ports never reach cnmac with a
usable media setup.
Enumerate CN71xx SGMII ports from pip/interface at N when that description
is present, carry the 1000x and disable-autonegotiation flags into the
per port state, and let cnmac seed fixed 1000baseT full duplex media for
that case. Ports that still use a normal SGMII PHY path continue to go
through cn30xxsmi_get_phy() and mii_attach() unchanged.
Tested on two CN71xx Octeon systems: Juniper SRX300, which uses
1000BASE-X DT ports, and Ubiquiti EdgeRouter 4, which does not.

When updating the ranges after an insertion or deletion, the range
should be up to and including the current line number.
This behavior is consistent with historic vi as well as modern vim.

grow the buffer to hold the sprintf'd rtable id by 8 bytes so it can hold
the full range an int can express.
the previous buffer was large enough since the rtable id is clamped to 0..
RT_TABLEID_MAX which is 255, however, it is a bit much to ask for analyzers -
including those in compilers - to detect that, 8 extra bytes on the stack
cost us effectively nothing, and it feels a bit more robust.

Use &nowake as ident in tsleep_nsec call instead of using a stack variable
for the same goal. Using &nowake is becomes clear that there is no wakeup
