New Revision: 248714
URL: http://svnweb.freebsd.org/changeset/base/248714
Log:
Convert the EDMA multicast queue code over to use the HAL method to set
the descriptor link pointer, rather than directly.
This is needed on AR9380 and later (ie, EDMA) NICs so the multicast queue
has a chance in hell of being put together right.
Tested:
* AR9380, AR9580 in hostap mode, CABQ traffic (but with other patches..)
