Hi Mark,
I have one question more. Driver stop function ( npe_stop ) works incorrect
after this function isn't any messages in QMgr and NPE don't receive frames.
When I comment ixEthAccPortDisable and registration of stop_callbacks it's
working fine ( after init start stack sends two times start, stop and start).
Have you any problem with driver in Redboot.
Best Regards,
Jerzy
