Bug 56959 – Added patch to support mpu and overhead to iproute2 ebuild

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description klavs klavsen 2004-07-13 15:47:47 UTC]

Hi guys,

Just got a good link from a fellow Linux user in my local LUG - whose used traffic shaping for many years, who used it, and says it gave him the possibility to use his ADSL at full speed (both ways) with no latency - which usually occurs otherwise (which is why wondershaper asks you to set max. perf a lot below your actual bandwidth AFAIK).
# new features in HTB which enables mpu and overhead - which is very nice for 
#adsl which is an ATM technology thing, where if you set your rules like this:
#
#class htb 1:1023 parent 1:102 leaf 1023: prio 3 quantum 1500 rate 95Kbit ceil #475Kbit burst 7b/8 mpu 48b overhead 5b cburst 2Kb/8 mpu 48b overhead 5b level 0
#
# it fits in the ATM frames that DSL uses, and does not incur the latency that 
# otherwise happens when the link is filled.
# i do not know if this is actually in 2.6.7 - he has backported HTB to 2.4.20 #because he uses wrtg54 and has to run 2.4.20 because of proprietary modules :(

Just changed it to enhancement :)

[Comment 2 SpanKY 2004-07-13 18:43:17 UTC]

ive e-mailed the upstream author of iproute2 since it still applies pretty cleanly to the latest 2.6.8_pre snapshot

[Comment 3 klavs klavsen 2004-07-14 00:43:50 UTC]

Thanks Spanky - could you let me know what the upstream author says - so I know when to expect the patch included :)

[Comment 4 SpanKY 2004-07-14 05:53:50 UTC]

yep, i'll post any response i get here

[Comment 5 SpanKY 2004-07-16 20:04:13 UTC]

just got an e-mail back from Stephen Hemminger; he's applied the patch and it'll be in the next release ;)
