Author: adrian Date: Thu Jun 23 02:38:36 2011 New Revision: 223459 URL: http://svn.freebsd.org/changeset/base/223459
Log: Break out most of the HAL related tweaks into a per-HAL instance, rather than global variables. This specifically allows for debugging to be enabled per-NIC, rather than globally. Since the ath driver doesn't know about AH_DEBUG, and to keep the ABI consistent regardless of whether AH_DEBUG is enabled or not, enable the debug parameter always but only conditionally compile in the debug methods if needed. The ALQ support is currently still global pending some brainstorming.
