Enable, This field is writeable, when bit 5 of
ext_cap_ena field in private register space is set.
This bit is RW only in function 0 and is RsvdP for
all other functions.
IDO Completion Enable, This field is writeable,
when bit ido_supported bit of private
device_capability_2 register is set. When this bit
is set, function is permitted to set ID based
Ordering Attribute of Completions it returns.
IDO Request Enable, This field is writeable,
when bit ido_supported bit of private
device_capability_2 register is set. When this bit
is set, function is permitted to set ID based
Ordering Attribute of Requests it initiates.
