- Change the PCI-X registers constants to be relative to the PCI-X PCI
capability rather than hardcoded offsets for a particular card. While I'm here, expand the constants some. - Change the ahd(4) driver to use pci_find_extcap() to locate the PCI-X capability to keep up with the first change. Reviewed by: scottl, gibbs (earlier version)
