    Subject[PATCH v6 10/10] PCI/AER: Add RCEC AER error injection support
    Date
    From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>

    The Root Complex Event Collectors(RCEC) appear as peers to Root Ports
    and also have the AER capability. So add RCEC support to the current AER
    error injection driver.
