[patch 06/18] PCI-X/PCI-Express read control interfaces: use them in myrinet
From: akpm@linux-foundation.org
Date: 2007-08-10 21:06:29
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.
