lsof doesn't recognize DCCP sockets

[Erik Inge Bolsø]

Binary package hint: lsof

To reproduce: start netsend listening on a DCCP socket.

$ netsend dccp receive

Do a lsof | grep netsend

knan@ip:~$ lsof | grep netsend
netsend 25588 knan cwd DIR 252,11 4096 352042 /home/bolso/ak-git/htrosbif
netsend 25588 knan rtd DIR 8,1 4096 2 /

netsend 25588 knan mem REG 8,1 136936 1561962 /lib/ld-2.11.1.so

netsend 25588 knan 2u CHR 136,1 0t0 4 /dev/pts/1
netsend 25588 knan 3u sock 0,6 0t0 685217 can't identify protocol

And the DCCP socket only shows up as "can't identify protocol".

I expected it to show up something like this UDPLITE example instead:

netsend 25572 knan 3u IPv4 681227 0t0 UDPLITE *:6666
