From: Ira Weiny <[email protected]>
The following patch series modifies the kernel MAD processing (ib_mad/ib_umad)
and related interfaces to send and receive Intel Omni-Path Architecture MADs on
devices which support them.
In addition to supporting some IBTA management classes, OPA devices use MADs
with lengths up to 2K. These "jumbo" MADs increase the performance of
management traffic.
To distinguish IBTA MADs from OPA MADs a new Base Version is introduced. The
new format shares the same common header with IBTA MADs which allows us to
share most of the MAD processing code when dealing with the new Base Version.
The patch series is broken into 3 main areas.
1) Add the ability for devices to indicate MAD size.
modify the MAD code to use this MAD size
2) Enhance the interface to the device agents to support larger and variable
length MADs.
3) Add capability bit to indicate support for OPA MADs
4) Add support for creating and processing OPA MADs
Changes for V4:
Rebased to latest Rolands for-next branch (3.19-rc4)
Fixed compile issue in ehca driver found with 0-day build.
