New Revision: 273868
URL: https://svnweb.freebsd.org/changeset/base/273868
Log:
MFC r273135 and r273867:
Update the OFED Linux compatibility layer and
Mellanox hardware driver(s):
- Properly name an inclusion guard.
- Fix compile warnings regarding unsigned enums.
- Fix compile warning regarding unused variable.
- Add two new sysctl nodes.
- Remove all empty linux header files.
- Make an error printout more verbose.
- Use "mod_delayed_work()" instead of
cancelling and starting a timeout.
- Implement more Linux scatterlist
functions.
- Don't forget to add "options OFED" to
the kernel configuration file before
using infiniband.
