next rule. Unlike a normally diverted packet no IP reassembly attemts are
made on tee'd packets and they are passed upwards totally unmodified.

results in programming the chip with the correct frequency, which in turn
allows devices to negotiate up to the full 20MB/s.

Malloc struct snapdata instead of just the lock.
Replace snapshot fields in cdev with pointer to snapdata (saves 16 bytes).

the loss of a page modified (PG_M) bit in a race between processors.
Quoting Tor:
One scenario where the old code could cause a lost PG_M bit is a
multithreaded linux program (or FreeBSD program using the
linuxthreads port) where one thread was starting a subprocess.
The thread doing fork() would call vmspace_fork(), which would then
call vm_map_copy_entry() which would call pmap_protect() on an area
possibly accessed by other threads.
Additionally, make the clearing of PG_M by pmap_protect() unconditional if
write permission is removed. Previously, PG_M could persist on a read-only
unmanaged page. That seems inconsistent and confusing.
