devip: ipgen() is incomplete

cat: can't open /mnt/term/net/tcp/0/status: '/mnt/term/net/tcp/0/status' does not exist

This is because the ipgen() function isn't complete enough for devstat() usage. I have this addressed locally - a patch is being prepared.

Furthermore, with the above problem fixed, the output from netstat program differs from usual:

cpu% netstat /mnt/term/net
tcp  0    yk       tcp/0        49508      17010      10.98.242.222
tcp  1    network    tcp/1        0          0          ::

This is because the status string is not the first word in reads from Qstatus. The proposed fix will be included in the patch.

With the correction applied:

cpu% ls -q /mnt/term/net/cs
(0006000000000002 0 00) /mnt/term/net/cs
cpu% ls -q /mnt/term/net/tcp/0/status

cpu% cat /mnt/term/net/tcp/0/status
