ARGUMENTS:      OsContext   - our adapter context.

RETURN:         Pointer to the allocated memory.

NOTES:          With the call to vmalloc it is assumed that this function will
                never be called in an interrupt context. vmalloc has the potential to
                sleep the caller while waiting for memory to become available.
