Commit Message

Wei Yang May 19, 2015, 1:35 a.m. UTC 
EEH address cache, which helps to locate the PCI device according to
the given (physical) MMIO address, didn't cover PCI bridges. Also, it
shouldn't return PF with address in PF's IOV BARs. Instead, the VFs
should be returned.

The patch restricts the address cache to cover first 7 BARs for the
above purposes.
