Fix two bugs (physio & cam) resulting by the confusion caused by this.

- Fix a bug in rl_rxeof() handler: in the case where the packet wraps
from the end of the receive buffer back to the beginning, we need to
insure that at least sizeof(ether_header) bytes make it into the first
mbuf. If we don't, then doing eh = mtod(m, struct ether_header *)
loses. To avoid this, we use m_pullup() to suck at least MHLEN -
RL_ETHER_ALIGN bytes into the first mbuf, which should also help
small packets fit into a single mbuf.

- Make the transmit threshold autotuning: start off with a small value
and jack it up when TX underruns are detected.
- Also improve TX error recovery: kick the chip in the head with a
reset/init sequence to make sure it recovers afer a transmit error.

isp_reset cases).
In order to make this work, I created a pseudo-PHY driver to deal with
Macronix chips that use the built-in NWAY support and symbol mode port.
This is actually all of them, with the exception of the original MX98713
which presents its NWAY support via the MII serial interface.
The mxphy driver actually manipulates the controller registers directly
rather than using the miibus_readreg()/miibus_writereg() bus interface
since there are no MII registers to read. The mx driver itself pretends
that the NWAY interface is a PHY locayed at MII address 31 for the sole
purpose of allowing the mxphy_probe() routine to know when it needs to
attach to a host controller.
- When setting/clearing promisc mode, just update the filter, don't
reset the whole interface.
- Call xl_init() in xl_ifmedia_upd() when setting miibus media modes. This
fixes a problem with the 3c905B-COMBO where switching from 10base5/AUI
or 10base2/BNC to a 10/100 mode doesn't always work right.
- Attempt to reset the interface in xl_init() so that we know we're getting
the receive and transmit rings reset properly.
* Change the hack used on the alpha for mapping devices into DENSE or
BWX memory spaces to a simpler one. Its still a hack and should be
a seperate api to explicitly map the resource.
* Add $FreeBSD$ as necessary.
Rather than teaching pci_ioctl about hoses, we just pass down a magic number
& let the platform code figure out what the hose is based on what the bus
number is.

The old algorithm was:
if class == storage and subclass != SCSI device must be IDE
This results in claiming 'raid' and 'other' storage devices as IDE,
which is typically not the case.

This file contained the structures for cfdata (old style config) and is no
longer used. It was included by most drivers.
It confuses the remote debugger as the definition of 'struct device' in
device.h is found before the one in bus_private.h.
For unknown devices the output will now be
pci0: unknown card (vendor=0x109e, dev=0x0878) at 14.1 irq 19
instead of
pci0: unknown card DD^0878 (vendor=0x109e, dev=0x0878) at 14.1 irq 19
Before this change, the code used to take the PCI vendor id and translate it
into a three letter ASCII name.
For PnP devices, the vendor id _does_ map to a nice ASCII name
(eg Creative Labs PnP ID maps to "CTL", ESS PnP ID maps to "ESS")
But there is no such mapping for PCI devices, as can be seen by the
example above where the Brooktree PCI vendor ID maps to "DD^"
The PCI Special Interest Group confirmed they do not have any mappings
from vendor ID to ASCII.

o Convert the driver to using bus_space. This allows alphas with
fxp's to boot, rather than panic'ing because rman_get_virtual()
doesn't really return a virtual address on alphas.
o Fix an alpha unaligned access error caused by some misfeature of
gcc/egcs: if link_addr & rbd_addr in the fxp_rfa struct are 32 bit
quantities, egcs will assume they are naturally aligned. So it will do
a ldl & some shifty/masky to twiddle 16 bit values in fxp_lwcopy().
However, if they are 16-bit aligned, the ldl will actually be done on
a 16-bit aligned value & we will panic with an unaligned access
error... Changing their definition to an array of chars seems to fix
this. I obtained this from NetBSD.
I've tested this on both i386 & alpha.

Add a slightly different safetybelt under nostop for tty drivers.
Add some missing FreeBSD tags
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.
This does not open any security hole, because the bpf core isn't loadable
The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.
Add a couple of missing FreeBSD tags.
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.
