This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

* Registers for the Adaptec AIC-6915 Starfire. The Starfire has a 512K
* register space. These registers can be accessed in the following way:
* - PCI config registers are always accessible through PCI config space
* - Full 512K space mapped into memory using PCI memory mapped access
* - 256-byte I/O space mapped through PCI I/O access
* - Full 512K space mapped through indirect I/O using PCI I/O access
* It's possible to use either memory mapped mode or I/O mode to access
* the registers, but memory mapped is usually the easiest. All registers
* are 32 bits wide and must be accessed using 32-bit operations.

#ifdef out the definition for the small packet RX ring. I ended up only using one RX ring because of the alignment issue, so we may as well save a few K of memory by not allocating space for it.

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.
