Description/Purpose
Maxium read request size specifies the
size for the device when acting as the
requestor. The device must not generate
read requests with a size larger this value.
Specifies mode for Active State Power
Management (ASPM), hardware-based
link power conservation mechanism.
Force L0 standby mode applies to a
single direction on the link.
Enabling extended synch feature forces
the transmission of additional ordered
sets when exiting the L0 state and when
in the recovery state. This mode provides
external devices monitoring the link time
to achieve bit symbol lock before the link
enter L0 state and resumes
communication.
