Add a new driver for the AMD PCnet/FAST, FAST+ and Home PCI adapters. Previously, these cards were supported by the lnc driver (and they still are, but the pcn driver will claim them first), which is fine except the lnc driver runs them in 16-bit LANCE compatibility mode. The pcn driver runs these chips in 32-bit mode and uses the RX alignment feature to achieve zero-copy receive. (Which puts it in the same class as the xl, fxp and tl chipsets.) This driver is also MI, so it will work on the x86 and alpha platforms. (The lnc driver is still needed to support non-PCI cards. At some point, I'll need to newbusify it so that it too will me MI.) The Am79c978 HomePNA adapter is also supported.

.It "pcn%d: chip is in D3 power state -- setting to D0"
This message applies only to adapters which support power
management.
Some operating systems place the controller in low power
mode when shutting down, and some PCI BIOSes fail to bring the chip
out of this state before configuring it.
The controller loses all of
its PCI configuration in the D3 state, so if the BIOS does not set
it back to full power mode in time, it will not be able to configure it
correctly.
The driver tries to detect this condition and bring
the adapter back to the D0 (full power) state, but this may not be
enough to return the driver to a fully operational condition.
If
you see this message at boot time and the driver fails to attach
the device as a network interface, you will have to perform a
warm boot to have the device properly configured.
.Pp
Note that this condition only occurs when warm booting from another
operating system.
If you power down your system prior to booting
.Fx ,
the card should be configured correctly.
