network_mgmt: Add ip_notify timer print. 

driver inclusion
category: cleanup
bugzilla: https://gitee.com/openeuler/kernel/issues/IAQT7G


CVE: NA

----------------------------------------------------------------------

1.Added an echo print to remind users of the current period time
for modifying the ip_notify timer.
2.When packets are counted, increase judgment for
'NET_XMIT_CN'/'-ENOMEM'/'-ENETDOWN' of return values.
