Author: adrian Date: Sun May 8 05:25:42 2011 New Revision: 221617 URL: http://svn.freebsd.org/changeset/base/221617 Log: * Add in a comment about ar5416InitUserSettings() potentially modifying AR_DIAG_SW. There's a hardware workaround which sets disabling some errors early at startup and clears said bits before the PCU begins receiving - it does this to avoid RX descriptor status errors. It's possible these bits aren't being completely properly twiddled in all instances; but in particular if the diag_reg HAL variable is set it won't be setting these bits correctly. I'll review this at some point. * Disable multicast search on mac address and key id - the driver doesn't use it at the moment and thus adhoc may be broken for merlin and later. * Change this to be for Merlin 1.0 (which from what I understand wasn't ever publicly released) to be more correct.
