Hi ALL:
       I'm using Kamikaze-47xx-2.6 (R6915) with BCM4704+Atheros wifi, it seems work fine but I found that I can not use sysctl to adjust some parameters--i.e.      TCP/UDP timeout
        I use vi to modify the file /etc/sysctl.conf, and load the conf with systcl -p, but some errors popup says:

sysctl: error: 'net.ipv4.ip_conntrack_tcp_timeouts' is an unknown key

sysctl: error: 'net.ipv4.ip_conntrack_udp_timeouts' is an unknown key

and check the /proc you will see the modification is not done. I also try modify&reboot, the file is changed, but the parameters remain old values.

does this mean that the sysctl is not functional at all, and I have to use "echo blabla > /proc/aa/bb/cc" to modify these settings?
or may be I modify a wrong file....

I want to change these because current setting is read from the "old" NVRAM parameters(which I already modified from factory default) and now I can not change NVRAM (unless a rewrite back to brcm 2.4?)
