Author: mav Date: Thu Nov 28 00:41:42 2019 New Revision: 355152 URL: https://svnweb.freebsd.org/changeset/base/355152 Log: MFC r354702: Make ntb(4) send bus_get_dma_tag() requests to parent buses passing real bus' child pointers instead of grandchilds. DMAR does not like requests from devices not parented directly by PCI.
