Log Message:
Commit workaround for hardware bug: 5701 chips running in PCI-X mode
require that the DMA receive buffers be aligned. The driver was
deliberately mis-aligning by 2 bytes, to force the layer-2/3
headers to 32-bit alignment.

Workaround: if chip is a 5701, and is in PCI-X mode, leave the DMA
buffers aligned.  If the host CPU requires alignment, copy the buffer
after reception to force aligment.

Tested  on an i386 in  PCI-X bus, with __NO_STRICT_ALIGNMENT forced off.

Patch and comments reworked  to minimize drift from
	FreeBSD if_bge.c rev 1.14.
