Currently the field nsvci_is_valid is set to 0 in the NSVC object returned by gprs_nsvc_create(). This was a semantic change probably introduced by commit 5e6d679d. As a result, NSVC created via the VTY have this flag set to 0 causing RESET_ACK messages to be rejected. This patch changes the default behaviour of gprs_nsvc_create() to always set this flag. So it must be set to 0 explicitely if needed which is more intuitive and thus less error prone. It fixes breaking connections from the Gbproxy to the SGSN.
