qeth: change default standard blkt settings for OSA
blkt settings (or LAN idle settings) for an OSA Express card determine when and how often an OSA Express card tells the operating system about new incoming packets. The semantic of these settings has changed starting with OSA Express3. Currently the qeth standard settings apply to OSA Express2 and older generations of OSA Express cards, while new generations of OSA Express cards require extra coding of their reasonable default. To cover future OSA Express generations the qeth default standard blkt setting is now the desired setting for OSA generations starting with OSA Express3, while the fixed set of older OSA Express cards receives its blkt settings explicitly.
