Comment 8 Nicolas Joly 2006-01-10 13:45:23 UTC 
Ok, i got it and it do solve the parsing problem. Thanks.

In the mean time, i noticed that with an interval value the counters are not
updated even if there some traffic on this interface:

Comment 10 Bob Johnson 2006-04-11 15:48:38 UTC 
This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 4.4 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 4.4 release.
Comment 12 Carl Speare 2006-05-30 19:00:02 UTC 
I also see this bug (netstat not updating statistics on a single interface, just
as in comment 8) on ES4u3 (using net-tools-1.60-37.EL4.6), and the original
issue is also present.

We'll definitely need ES4u4 for the fixup.
