This workaround is for 5714/5715 controllers and is not actually a MAC controller bug but an issue with the embedded PCIe to PCI-X bridge in the device. This change uses bus_dmatag_subregion(), so this workaround won't work on some archs which doesn't support bus_dmatag_subregion().
$NetBSD: README,v 1.3 1998/08/15 03:02:46 mycroft Exp $ This directory contains files which are used during PCI configuration and PCI device drivers. Eventually, most of the device drivers and some of the configuration support should become machine-independent and be moved to a more general location. The configuration support was implemented according to the `PCI Local Bus Specification, Production Version, Revision 2.0' dated April 30, 1993. Section numbers referred to in the code may be specific to that edition of the specification. Some attempt has been made to insure that the code works on rogue machines where the BIOS doesn't do its job, but in general I can't guarantee that. -- - Charles M. Hannum NetBSD group August 8, 1994
