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