enable_system_error_only_for_aer:
Applies only to root ports. For Dev#0 in DMI mode, this bit 
is to be left at default value always.When this bit is set, the 
PCI Express errors do not trigger an MSI or Intx interrupt, 
regardless of the whether MSI or INTx is enabled or not. 
Whether or not PCI Express errors result in a system event 
like NMI/SMI/PMI/CPEI is dependent on whether the 
appropriate system error or override system error enable 
bits are set or not.
See section titled PCI Express Error Reporting Specifics in 
the RAS chapter for details of how this bit interacts with 
other control bits in signalling errors to the IIO global error 
reporting logic.
When this bit is clear, PCI Express errors are reported via 
MSI or INTx and/or NMI/SMI/MCA/CPEI. When this bit is 
clear, and ‘System Error on Fatal Error Enable’ bit in 
ROOTCON register is set, then NMI/SMI/MCA is (also) 
generated for a PCI Express fatal error. Similar behavior for 
nonfatal and corrected errors.
