Analyze and fix the following issue in the Linux kernel code: syncppp: Fix crashes.
Problem Details: The syncppp layer wants a mid-level netdev private pointer. It was using netdev->priv but that only worked by accident, and thus this scheme was broken when the device private allocation strategy changed. Add a proper mid-layer private pointer for uses like this, update syncppp and all users, and rem...

Problem Details: The loop in ipath_kreceive() that processes packets increments the loop-index 'i' once too often, because the exit condition does not depend on it, and is checked after the increment.
