You don't really specify the line rate. Line-rate is the speed which will cause entrie available BW to be used.
To answer the underlying question, when you lower the rate, you specify shaping value and burst.
Shaping is discussed for example here:
http://www.cisco.com/en/US/tech/tk543/tk545/technologies_q_and_a_item09186a00800cdfab.shtml#policing
Example
bdsol-6248-06-A(nxos)# show run | section Gold
policy-map type queuing org-root/ep-qos-Gold_QoS
class type queuing class-default
bandwidth percent 100
shape 5000000 kbps 65000
and when using line rate.
bdsol-6248-06-A(nxos)# show run | section Platinium
policy-map type queuing org-root/ep-qos-Platinium_5124
class type queuing class-default
bandwidth percent 100
shape 10000000 kbps 5124

Thank you, Marcin.
Quick question -
Once you set the line rate as 5GB/s, would that be a hard limit on that PCIe device? or can the device get more than the specified bandwidth?
