Subject[MPTCP][PATCH net-next 06/16] selftests: mptcp: add ADD_ADDR mibs check function
Date
This patch added the ADD_ADDR related mibs counter check function
chk_add_nr(). This function check both ADD_ADDR and ADD_ADDR with
echo flag.

The output looks like this:

07 unused signal address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
08 signal address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
09 subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
10 multiple subflows and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
11 remove subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
