mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Better wording.

Use the newly brought %U macro.

Xref altq(4) for drivers that support it according to altq(4).

- move list of supported devices into a HARDWARE section
- mention which chip the devices use (where known)
- bump document date

Mechanically kill hard sentence breaks and double whitespaces.

Spelling fixes.

Capitalize "Fast Ethernet" and "Ethernet" consistently.

Synchronize manual page with hardware notes and reformat list of
supported devices.

Xref miibus(4).

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

Mention that the Netgear FA311 is supported as well as the FA312.

Fix up the sis.4 man page per Sheldon Hearn:

* Clear the Os macro, which is assumed gracefully at run-off time.
* Use quotes to reduce the long name description (Nd) to a single
argument.
* Use meaningful arguments to the -width option of the Bl macro.
* Mark rc.conf up with Xr instead of Pa so that it is obvious that
further help on that file is available.
* Explicitly indicate that mediaopt is a command modifier (Cm) of
the ifconfig(8) utility.
* Do not mark up half-duplex and full-duplex as arguments (Ar),
since they are allowed values for an argument.
* Fix various grammar and spelling mistakes.

Add support for the National Semiconductor DP83815 fast ethernet
controller chip. This chip is currently being used on the NetGear
FA312-TX adapter, which I guess is a replacement for the FA310-TX
(PNIC-based).

I added support for this chip by modifying the sis driver since
the SiS 900 and the NS DP83815 have almost the same programming
interface (the RX filter programming and PHY access methods are
different, but the general configuration, DMA scheme and register
layout are identical).

I would have had this done a lot sooner, but getting the damn MAC
address out of the EEPROM proved to be more complicated than expected.

Move netgraph node type man pages from section 8 to section 4.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Add a reference to ng_ether(8).

Second round of config related changes to the manpages.

device blah0 -> device blah for PCI devices and busses.

Add/fix controller miibus0/device miibus0 stuff here too.

* remove i386 specific mark
* some style and syntax fixes
* some duplicated $FreeBSD$ tags removed

This commit adds driver support for the Silicon Integrated Systems
SiS 900 and SiS 7016 PCI fast ethernet chipsets. Full manuals for the
SiS chips can be found at www.sis.com.tw.

This is a fairly simple chipset. The receiver uses a 128-bit multicast
hash table and single perfect entry for the station address. Transmit and
receive DMA and FIFO thresholds are easily tuneable. Documentation is
pretty decent and performance is not bad, even on my crufty 486. This
driver uses newbus and miibus and is supported on both the i386 and
alpha architectures.
