E.g. ipaccess use reset/block on udp<br>and is a dynamic connection.<br>A single NS Entity can only support one dialect. This can be later<br>used to protect a NS Entity against dynamic NS virtual circuits of a<br>different type.<br><br>It further allows a bind to support multiple dialects at the same time.<br><br>Change-Id: Ia118bb6f994845d84db09de7a94856f5ca573404<br>---<br>M include/osmocom/gprs/gprs_ns2.h<br>M src/gb/gprs_ns2.c<br>M src/gb/gprs_ns2_fr.c<br>M src/gb/gprs_ns2_internal.h<br>M src/gb/gprs_ns2_udp.c<br>M src/gb/gprs_ns2_vty.c<br>M src/gb/libosmogb.map<br>7 files changed, 68 insertions(+), 28 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/libosmocore refs/changes/84/21484/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/include/osmocom/gprs/gprs_ns2.h b/include/osmocom/gprs/gprs_ns2.h</span><br><span>index 4575329..ccb1a94 100644</span><br><span>--- a/include/osmocom/gprs/gprs_ns2.h</span><br><span>+++ b/include/osmocom/gprs/gprs_ns2.h</span><br><span>@@ -32,6 +32,13 @@</span><br><span> NS2_VC_MODE_ALIVE,</span><br><span> };</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+enum gprs_ns2_dialect {</span><br><span style="color: hsl(120, 100%, 40%);">+ NS2_DIALECT_STATIC_ALIVE,</span><br><span style="color: hsl(120, 100%, 40%);">+ NS2_DIALECT_STATIC_RESETBLOCK,</span><br><span style="color: hsl(120, 100%, 40%);">+ NS2_DIALECT_IPACCESS,</span><br><span style="color: hsl(120, 100%, 40%);">+ NS2_DIALECT_SNS,</span><br><span style="color: hsl(120, 100%, 40%);">+};</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span> /*!
