No I haven´t.
Meanwhile I have also gone through a checked out and build
openwrt buildtree with all feeds and searched for the option
with grep.

I only found the following information:
* tcp_syncookies -> found in sysctl of the kernel and fw4
* tcp_ecn -> found in sysctl of the kernel and fw4
* accept_redirects -> found in sysctl of the kernel and fw4
* accept_source_route -> found in sysctl of the kernel and fw4

Maybe the options were used in old openwrts to configure the
kernel's sysctl?
