33  * simple netstat based on snmp/mib-2 interface to the TCP/IP stack
34  *
35  * NOTES:
36  * 1. A comment "LINTED: (note 1)" appears before certain lines where
37  *    lint would have complained, "pointer cast may result in improper
38  *    alignment". These are lines where lint had suspected potential
39  *    improper alignment of a data structure; in each such situation
40  *    we have relied on the kernel guaranteeing proper alignment.
41  * 2. Some 'for' loops have been commented as "'for' loop 1", etc
42  *    because they have 'continue' or 'break' statements in their
43  *    bodies. 'continue' statements have been used inside some loops
44  *    where avoiding them would have led to deep levels of indentation.
45  *
46  * TODO:
47  *	Add ability to request subsets from kernel (with level = MIB2_IP;
48  *	name = 0 meaning everything for compatibility)
