This allows packets that have no PDP to go though, patch from Lionel Gauthier. 2) According to Note 0 of Figure 2 in Section 6 of 3GPP TS 29.060 v13.5.0 Release 13, always set GTPv1 reserved bit to zero. This may cause interoperability problems, patch from Harald Welte. Please, apply, thanks a lot!
