82546GB(0x107a), 82571GB(0x105f), 82572EI(0x107e). Tested on SERDES 82580(0x150e (Winyao SERDES SFP)) and 82580(0x150e) as regression test: - Fix a bug that the link can't detect in link interrupt function for non-SERDES fiber. When the signal is detected & STATUS_LU == 0 & RXCW == 0, it's required to set CTRL_SLU and CTRL_FD bit. wm_check_for_link() is the function to do it. If a link status change interrupt occured, call wm_check_for_link() before checking current link staus. - Fix a bug that 82542 misunderstand fiber's signal detection. CTRL_SWDPIN(1) is used for fiber's signal and it's value is reversed only on 82543 and 82544. Simplify the code and move it into a new function wm_tbi_havesignal() and use it.
$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
