Subject: [PATCH net-next 0/2] tcp/dccp: refine source port selection

This patch series leverages IP_LOCAL_PORT_RANGE option
to no longer favor even source port selection at connect() time.

This should lower time taken by connect() for hosts having
many active connections to the same destination.

Eric Dumazet (2):
  inet: returns a bool from inet_sk_get_local_port_range()
  tcp/dccp: change source port selection at connect() time
