NetBSD/sys/dev/pci/if_tlp_pci.c
castor b6dd28b4ce Support some differences in the Macronix 98715AEC-C and E chips from the other 
98715* series.

The MX98715AEC-[C,E] use a different location in the serial eerom for
LED control, and programming it with the original location's values
caused unpredictable behavior.

Also, start integrating fixes where media changes on an adapter
under load may fail.  There's more work to be done here, but I need
to sort out our internal changes a little more carefully.
