NAME
       ibv_inc_rkey - creates a new rkey from the given one

SYNOPSIS
              #include <infiniband/verbs.h>

              uint32_t ibv_inc_rkey(uint32_t rkey);

DESCRIPTION
       ibv_inc_rkey() Increases the 8 LSB of rkey and returns the new value.

RETURN VALUE
       ibv_inc_rkey() returns the new rkey.

NOTES
       The verb generates a new rkey that is different from the previous one
       on its tag part but has the same index (bits 0xffffff00).  A use case
       for this verb can be to create a new rkey from a Memory window's rkey
       when binding it to a Memory region.
