please enable CoDel in 3.6 kernel #165

Why can't you just rebuild the kernel? Gordon |
|
well, of course i can. i just can't see any reason why this is not enabled by default... ;-) |
|
Hi there, |
|
hi! ...not yet since i've had some other issues with the -next kernel. ...but anyway, compile time delta for this module is negligible. ...and compile time shouldn't be an obstacle anyway imho (you compile only once). |
|
This is enabled in "next" firmware tree: |
|
thank you very much! closing... |

…ap() commit aef4885 upstream. Error report likely result in IO so it is bad idea to do it from atomic context.

the config should say:
CONFIG_NET_SCH_CODEL=m
CONFIG_NET_SCH_FQ_CODEL=m
...so i can use my raspi as a low-latency router. thank you very much!
