dpaa2-eth: Avoid unbounded while loops
Throughout the driver there are several places where we wait indefinitely for DPIO portal commands to be executed, while the portal returns a busy response code. Even though in theory we are guaranteed the portals become available eventually, in practice the QBMan hardware module may become unresponsive in various corner cases. Make sure we can never get stuck in an infinite while loop by adding a retry counter for all portal commands. Signed-off-by:Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by:
