Hi Pali,

Another possible way of doing this might have been to alias the macro:

#define XGENE_PCIE_VENDORID PCI_VENDOR_ID_AMCC

Not sure if this would be more or less confusing - I certainly had to go
and look up what "AMCC" was. Only to found out they got sold few years
ago, and such...

Nothing to change here, though.

Thank you!
