After upgrade to 2.6.16.20 from 2.6.11 I discovered that no dynamic
interfaces (vlans, tunnels) appear under /proc/sys/net/ipv4/conf/.
/proc/sys/net/ipv6/conf/ is OK.
Bug? Or feature?
with my best wishes,

OK, realised out that it's feature. Entries in /proc/sys/net/*/conf/ are
not created if interface doesn't have at least one ipv4/ipv6 address.
I can think of workarounds for most of problems (although it breaks a hell
lot of software here), but how I suppose to configure ipv6 settings for
interfaces which have to obtain global ipv6 address via autoconf so that
it will work even if cable is not plugged in? I did via /etc/sysctl.conf,
but now ... machine boots with no link => no link-local address =>
no /proc/sys/net/ipv6/conf/<interfce> => configuration fails.
regards,

Just realized (via practical experience) that same question applies to
interfaces configured via dhcp.
