Make thelimited information in config space available. Note the Read/WriteMailbox registers themselves are not currently parsed as the usefulnessof accessing one dword of a protocol is probably limited.In future, operating systems may provide means to safely query thesupported protocols, but those have not yet been defined.Example output: Capabilities: [100 v1] Data Object Exchange DOECap: IntSup+ Interrupt Message Number 001 DOECtl: IntEn+ DOESta: Busy- IntSta- Error- ObjectReady+[1] PCIe r6.0, sections 6.30 and 7.9.24Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> List of files: /pciutils/tests/cap-doe Thu, 10 Feb 2022 16:19:45 +0000 Jonathan Cameron <Jonathan.Cameron@huawei.com>
