The ILOST error is always piggybacked onto an existing interrupt descriptor which can have an event, an error, or
both bit fields set.

errors.
Errors reported in the buffer status descriptor are also reported in the interrupt descriptor. The occurrence in
shared memory of a buffer status descriptor and the interrupt descriptor conveying the same error condition is
indeterminate. The occurrence of an interrupt does not imply host ownership of the buffer status descriptor. The
host must always confirm ownership of the buffer status descriptor before overwriting it.
