* Modification History: *
* *
* int_stats.c : Get network statistics from the dlpi device *
* On 10.20 only get a mib_ifEntry, on 11.0 this is followed *
* by an mib_Dot3StatsEntry. Accessing the latter structure *
* is left as an exercise for the reader, the struct is defined *
* in /usr/include/sys/mib.h along with mib_ifEntry. *
* *
* Author: Jon Dewis, SPP 3/26/98 *
* (With ackn to 'lanadmin' source code and streams class notes) *
* *
* 24-June-1998 Add mib3 stats (AJD) when compiling *
* for 11.0 ensure HP_UX11 macro defined *
* e.g. cc -o int_stats -DHP_UX11 int_stats.c *
* 16-Dec-1999 Change to obviate need for lanscan to get *
* nmid - thus assumes any old nmid will do *
* and just iterates thru the 1st 100 possibilities *
* (MAX_NMID). Works on 10.20 and 11.0 *
* Dec 2003 Modified by Roshan Sequeira roshan.sequeira@hp.com, *
* to get network statistics for the nload port to HP-UX. *
* Original code available at *
* http://h21007.www2.hp.com/dspp/tech/tech_TechDocumentDetailPage_IDX/1,1701,2599,00.html
