This is part 1 of big network cleanup / DM conversion.
The dc2114x/rtl8139/pcnet/tulip PCI adapter drivers received checkpatch
cleanups in preparation for DM conversion. The smc911x is converted to
DM completely. The dwc_eth_qos cache fixes are applied.

28 Dec 2002 ken_yap@users.sourceforge.net (Ken Yap)
Put in virt_to_bus calls to allow Etherboot relocation.
06 Apr 2001 ken_yap@users.sourceforge.net (Ken Yap)
Following email from Hyun-Joon Cha, added a disable routine, otherwise
NIC remains live and can crash the kernel later.
4 Feb 2000 espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
Shuffled things around, removed the leftovers from the 8129 support
that was in the Linux driver and added a bit more 8139 definitions.
Moved the 8K receive buffer to a fixed, available address outside the
0x98000-0x9ffff range. This is a bit of a hack, but currently the only
way to make room for the Etherboot features that need substantial amounts
of code like the ANSI console support. Currently the buffer is just below
0x10000, so this even conforms to the tagged boot image specification,
which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
interpretation of this "reserved" is that Etherboot may do whatever it
likes, as long as its environment is kept intact (like the BIOS
variables). Hopefully fixed rtl_poll() once and for all. The symptoms
were that if Etherboot was left at the boot menu for several minutes, the
first eth_poll failed. Seems like I am the only person who does this.
First of all I fixed the debugging code and then set out for a long bug
hunting session. It took me about a week full time work - poking around
various places in the driver, reading Don Becker's and Jeff Garzik's Linux
driver and even the FreeBSD driver (what a piece of crap!) - and
eventually spotted the nasty thing: the transmit routine was acknowledging
each and every interrupt pending, including the RxOverrun and RxFIFIOver
interrupts. This confused the RTL8139 thoroughly. It destroyed the
Rx ring contents by dumping the 2K FIFO contents right where we wanted to
get the next packet. Oh well, what fun.
18 Jan 2000 mdc@thinguin.org (Marty Connor)
Drastically simplified error handling. Basically, if any error
in transmission or reception occurs, the card is reset.
Also, pointed all transmit descriptors to the same buffer to
save buffer space. This should decrease driver size and avoid
corruption because of exceeding 32K during runtime.
28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
rtl_poll was quite broken: it used the RxOK interrupt flag instead
of the RxBufferEmpty flag which often resulted in very bad
transmission performace - below 1kBytes/s.
