e1000: Serialize 82579 CSR writes with the Management Engine
The 82579 PCIm2PCI arbiter can acknowledge a host MAC CSR write while
the Management Engine is accessing another CSR. The host write can be
lost; subsequent target accesses may no longer be claimed by the MAC and
can hang the system.
For 82579 controllers with valid management firmware, wait for the ME
CSR access indication before every MAC CSR write. Keep the wait bounded
and use DELAY because writes occur in interrupt and datapath contexts.
Verify every transmit and receive tail write. If a tail does not hold
the requested value, disable its datapath direction and request a full
iflib reset.
Keep the ordinary register-write path as a direct MMIO write behind a
predicted per-device gate. Contain the wait and tail recovery in the
82579 slow path rather than adding tail-specific accessors and state to
the rest of the e1000 family.

sysutils/fluent-bit: Restore libyaml dependency (unbreak)
The update to 5.1.2 replaced the libyaml LIB_DEPENDS entry with libzstd
instead of adding it. FLB_CONFIG_YAML is still enabled by default, so
the FLB_HAVE_LIBYAML configure test failed and the build stopped with
"YAML development dependencies required for YAML configuration format
handling".
Both libraries are needed: the resulting binary links against
libyaml-0.so.2 and libzstd.so.1.

iavf: Probe the Hyper-V VF device ID
The shared code already recognizes IAVF_DEV_ID_VF_HV and handles it
through the regular iavf register and virtchnl paths, but the PCI probe
table omits it. Add the missing entry so the driver attaches.

apple_bce: require usb(4) for vhci functionality
The vhci portion of the driver relies on usb(4) for both constants and
functionality. Add an explicit dependency on usb(4) in `files.amd64` so
it builds properly 100% of the time in a static kernel config.

grep(1): optimize -w/--word-regexp word boundary check
The -w option checks word boundaries before and after each potential
match by decoding the adjacent character. This was done via the
heavyweight sscanf(3) with "%lc", which goes through the full scanf
parser and locale-aware mbrtowc(3) machinery even for simple ASCII.
Replace with a three-tier fast path:
1. ASCII bytes (< 0x80): simple isalnum(3) / '_' comparison
2. UTF-8 continuation bytes (0x80-0xBF): interior bytes of a multi-byte
character are always word characters -> no further decoding needed
3. Multi-byte start bytes (>= 0xC0): decode with mbrtowc(3) directly
instead of sscanf(3)/%lc, avoiding scanf parser overhead
Benchmark with ministat(1) (10 runs each):
Worst-case ASCII (100k lines of 100 'a' chars, -w 'a'):
Difference at 95.0% confidence: -15.3% +/- 3.1%

grep: periodic timer-based fflush instead of unconditional per-line flush
Replace the unconditional fflush(stdout) in grep_printline and
procmatches with a periodic timer that flushes at most once every
100ms. This preserves interactive responsiveness (grep | tee,
grep | tail -f) while avoiding 1M+ write(2) syscalls when
processing large inputs.
The flush interval is tracked via clock_gettime(CLOCK_MONOTONIC)
and a static timespec. --line-buffered continues to flush
immediately via setlinebuf(3), as before.
Benchmark on 1M lines (37MB output to file):
unconditional fflush: 1.90s (sys 1.22s)
periodic 100ms timer: 0.49s (sys 0.007s)
