s390/qeth: don't apply takeover changes to RXIP
When takeover is switched off, current code clears the 'TAKEOVER' flag on all IPs. But the flag is also used for RXIP addresses, and those should not be affected by the takeover mode. Fix the behaviour by consistenly applying takover logic to NORMAL addresses only. Signed-off-by: Julian Wiedmann <jwi@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
