Author: markj Date: Thu Nov 7 23:36:46 2019 New Revision: 354507 URL: https://svnweb.freebsd.org/changeset/base/354507 Log: iwm: Enable all 31 tx queues. For now iwm only ever uses queue 0 and the management queue, but my 9560 raises a software error interrupt during initialization if this flag is not set. iwlwifi sets it for all 7000- and 8000-series hardware, so we might as well do it unconditionally.
