[patch 06/18] PCI-X/PCI-Express read control interfaces: use them in myrinet

From: "Peter Oruba" <redacted>

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.
