Contact: haver@linux.vnet.ibm.com
|
|
Description: Default VF timeout 250ms. Testing might require 1000ms.
|
|
Using 0 will use the cards default value (whatever that is).
|
|
|
|
The timeout depends on the max number of available cards
|
|
in the system and the maximum allowed queue size.
|
|
|
|
The driver ensures that the settings are done just before
|
|
the VFs get enabled. Changing the timeouts in flight is not
|
|
possible.
|
|
Only available for PF.
