resubmit(,1)：resubmit to table 1

hard_age=secs:

The integer number of seconds since the flow was added or  modified.  hard_age is displayed only if it differs from the integer part of duration.

idle_age=secs:
The integer number of seconds that have passed without any packets passing through the flow.

duration=secs:
The  time,  in  seconds,  that  the entry has been in the table.secs includes as much precision as the switch provides, possibly to nanosecond resolution.

n_packets:
The number of packets that have matched the entry.
n_bytes:
The  total  number  of  bytes from packets that have matched the entry.

priority=value:
The  priority at which a wildcarded entry will match in comparison to others.  value is a number between 0  and  65535,  inclusive.   A higher value will match before a lower one.  An exactmatch entry will always have priority over an  entry  containing wildcards,  so it has an implicit priority value of 65535.  When adding a flow, if the field is not specified, the flow's  priority will default to 32768.

idle_timeout=seconds
Causes  the  flow to expire after the given number of seconds of inactivity.  A value of 0 (the default)  prevents  a  flow  from expiring due to inactivity.
hard_timeout=seconds
Causes  the  flow  to  expire after the given number of seconds, regardless of activity.  A value of 0 (the  default)  gives  the flow no hard expiration deadline.
