Subject: PCI-X/PCI-Express read control interfaces: use them in qla2xxx
From: "Peter Oruba" <peter.oruba@xxxxxxx>
These driver changes incorporate the proposed PCI-X / PCI-Express read byte
count interface. Reading and setting those valuse doesn't take place
"manually", instead wrapping functions are called to allow quirks for some
PCI bridges.
