Apart from minor cleanup of the text, it should document

RELENG_6 has some minor differences there in the way automatic
loading/unloading is handled, but hopefully this should be
fixed by MFC time.
The examples come from Max Laier and Sam Leffler.

The original DHCP specification includes a route option but it supports

width for each static route. A variable length encoding is used to minimize
the size of this option.

Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
needs different handling than the integrated ones in terms of
speed detection. There was a bogus test based on the parent
device driver name string controlling which speed register to
query. That test began failing when the rl driver was split into
separate rl and re drivers some time ago. Apparently nobody ever
noticed because the buggy code only executes if NWAY negotiation
failed. Since we happen to be testing with an ancient dumb hub
rather than a modern switch, we found it.
To fix it all, have the attach() routine notice whether we're
dealing with an integrated PHY or an RTL8201L and store that info
in a struct accessible to the status() routine that needs to know
which register to query.
I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

variable to avoid invalid constraints in dead code. Use an array of
u_char's (inside a struct) instead of a char/short/int/long variable so
that the variable and its accesses can be spelled in the same way in all
cases and code doesn't need to be cloned just to hold the spelling
differences.
Fixed strict-aliasing errors in PCPU_SET() and in the amd64 PCPU_GET().
Cast to (void *) as in rev.1.37 of the i386 version where the errors
were fixed for the i386 PCPU_GET() only. It would be more correct to
copy to and from the temp. variable using memcpy(), but then an
ifdef tangle would be required to ensure using the builtin memcpy().
We depend on fairly aggressive optimization to put the temp. variable
only in a register despite it being copied using
*(type *)(void *)&anothertype and could depend on this when using
memcpy() too. This seems to work right even for -O0, but the -O0 case
has not been completely tested.
This change gives identical object code for all object files in LINT
on amd64 (except for one file with a __TIME__ stamp). For LINT on
i386 it gives unimportant differences in instruction order and padding
in a few object files. This was only tested for -O.
This change (actually a previous version of it) gives the following
reductions in the number of object files in LINT that fail to compile
with -O2 but without the -fno-strict-aliasing kludge:
- amd64: 29 (down from 211)
- i386: 36 (down from 47)
gcc-3.4.6 actually allows the invalid constraints that result from not
using the temp. variable, at least with -O[1-2], but gcc-3.3.3 crashes
on them and I don't want to depend on compiler bugs.
