Enable the read DMA engine's PCI read request burst length long burst
mode (4KB) for PCIe chips. This resolves the poor TX performance for
the PCIe chips. The result being a bit under double the TX performance
on a Gig connection (roughly 495 Mb/s -> 940 Mb/s).
Tested by reyk@, sthen@, brad@ and a few end users.
