29  * simple netstat based on snmp/mib-2 interface to the TCP/IP stack
30  *
31  * NOTES:
32  * 1. A comment "LINTED: (note 1)" appears before certain lines where
33  *    lint would have complained, "pointer cast may result in improper
34  *    alignment". These are lines where lint had suspected potential
35  *    improper alignment of a data structure; in each such situation
36  *    we have relied on the kernel guaranteeing proper alignment.
37  * 2. Some 'for' loops have been commented as "'for' loop 1", etc
38  *    because they have 'continue' or 'break' statements in their
39  *    bodies. 'continue' statements have been used inside some loops
40  *    where avoiding them would have led to deep levels of indentation.
41  *
42  * TODO:
43  *	Add ability to request subsets from kernel (with level = MIB2_IP;
44  *	name = 0 meaning everything for compatibility)
