OFED: Various changes from Linux 4.12

2026-06-24T19:30:55+00:00

Most of the changes involve renaming InfiBand address handles (AH) to
RDMA address handles including renaming various types and functions.
Address handles now also include type-specific fields and a set of
wrapper accessor functions for getting and setting fields.  For some
of the type and function renames, drivers in sys/dev had to be updated
directly (typically via sed).

This contains changes from the following Linux commits:

Some of the registers added in a172f9e5b3cf are not directly accessible
and should be avoided.

cxgbe(4): Improvements to the slow interrupt handler

2026-05-28T19:05:57+00:00

* Add a flag to indicate that an INT_CAUSE should not be cleared
  automatically in the generic handler.  This is to ensure correct
  operation of some INT_CAUSEs that are related to each other and must
  be cleared in a certain order.
* Add decode for many more INT_CAUSE registers.
