Subject: Question about QOS
Date: Tue, 26 Apr 2005 11:16:33 +0200	[thread overview]
Message-ID: <426E06F1.9000105@6wind.com> (raw)

I set CONFIG_NET_SCH_CLK_GETTIMEOFDAY in my kernel. The macro 
PSCHED_TDIFF_SAFE calculates
the difference between two timestamps and uses the function 
psched_tod_diff() to do this.
If the clock is readjusted (due to ntp for example), this function can 
return a negative number
(if bound > 1000000) and then the flow is blocked by the kernel. Am I 
right ? or I miss
something ? Is this a bug ?


Thanks
Nicolas
