SVN rev 215891 on 2010-11-26 21:01:21Z by marius
MFC: r215722
- Fix and enable support for flow control.
- Partially revert r172334; as it turns out the DELAYs in gem_reset_{r,t}x()
are actually necessary although bus space barriers and gem_bitwait() are
used, otherwise the controller may trigger an IOMMU errors on at least
sparc64. This is in line with what Linux and OpenSolaris do.
