Description

Export:

$ lnetctl export --backup
net:
-     net type: tcp1
      local NI(s):
      -     interfaces:
                  0: eth1
            tunables:
                  peer_timeout: 180
                  peer_credits: 8
                  peer_buffer_credits: 0
                  credits: 256
            lnd tunables:
                  conns_per_peer: 1
                  timeout: 49
                  tos: -1
            CPT: "[0,1,2,3,4]"
-     net type: tcp2
      local NI(s):
      -     interfaces:
                  0: eth2
            tunables:
                  peer_timeout: 180
                  peer_credits: 8
                  peer_buffer_credits: 0
                  credits: 256
            CPT: "[0,1,2,3,4]"

lnd tunables is missing for tcp2. When tcp1 is removed, right values are shown for tcp2.
