Subject: Re: RFC: consistent disable_xfrm behaviour

Hello!

> Alexey, do you remember what the original intent of this was?

disable_policy was supposed to skip policy checks on input.
It makes sense only on input device.

disable_xfrm was supposed to skip transformations on output.
It makes sense only on output device.

If it does not work, it was done wrong. :-)

As I see it, root of the problem is that DST_NOXFRM flag
is calculated using wrong device. out_dev should be used
in __mkroute_input(). It looks as a cut-n-paste error, the code
was taken from output path, where it is correct.
