[NET]: Fix NAPI completion handling in some drivers.
In order for the list handling in net_rx_action() to be correct, drivers must follow certain rules as stated by this comment in net_rx_action(): /* Drivers must not modify the NAPI state if they * consume the entire weight. In such cases this code * still "owns" the NAPI instance and therefore can * move the instance around on the list at-will. */ A few drivers do not do this because they mix the budget checks with reading hardware state, resulting in crashes like the one reported by takano@axe-inc.co.jp. BNX2 and TG3 are taken care of here, SKY2 fix is from Stephen Hemminger. Signed-off-by: David S. Miller <davem@davemloft.net>
