ldp中ldp global處理iff介面下標過程

global是ldp_top的屬性，屬性名是

mpls_cfg_handle h;

retval = ldp_event(ldp->h, socket, socket->extra,

其中ldp即ldp_top

2ldp_global *g = (ldp_global*)handle;

其中g即ldp->h

在ldp_new的時候，針對new->h（即g）的處理有，

（3.1）初始化iff列表

(3.2) 設定管理狀態，與iff無關

(3.3) ldp_cfg_if_addr_set

似乎是連上了就傳送tcp，fixme

以上與iff增加無關

4 ldp_if_create

這是增加iff
