[Devel] [PATCH rh7] l2tp: Drop VE_FEATURE_PPP feature test

[Cyrill Gorcunov]

Actually if we're to support l2tp control via VE_FEATURE_PPP
we need more than plain bit test but the whole logic converted
from pcs6 code (which implies tunnel list and such).

As far as I know we don't have the plans at moment to control
l2tp this way so lets rip this code out otherwise there is
a net leak (because net_generic with @pppol2tp_net_id
always return nil and proc entry never released).
