Florent Fourcot Nov. 5, 2013, 2:28 p.m. UTC 
If the last RFC 6437 does not give any constraints
for lifetime of flow labels, the previous RFC 3697
spoke of a minimum of 120 seconds quarantine
for a flow label.

The maximum linger is currently set to 60 seconds
and does not allow this configuration without
CAP_NET_ADMIN right.

This patch increases the maximum linger to 150
seconds, allowing more flexibility to standard
users.
