What:           /sys/kernel/debug/genwqe/genwqe<n>_card/vf<0..14>_jobtimeout_msec
Date:           Oct 2013
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.
