New Revision: 236468
URL: http://svn.freebsd.org/changeset/base/236468
Log:
MFC: r236061
- When creating the DMA tag for user data, don't ask for more segments
than required for handling MAXPHYS and report the resulting maximum
I/O size to CAM instead of implicitly limiting it to DFLTPHYS.
- Move the variables of sym_action2() out of nested scope as required
by style(9) and remove extraneous curly braces.
- Replace a magic value for PCIR_COMMAND with the appropriate macro.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
Tested with a HBA donated by wilko.
