infiniband 的dhcp

infiniband 的dhcp server不能用官網下載的dhcp server .是有修改的
我從ubuntu 14.04.3下載source code
apt-get source isc-dhcp

檢查
/common/lpf.c
+/* Default broadcast address for IPoIB */
+static unsigned char default_ib_bcast_addr[20] = {
+     0x00, 0xff, 0xff, 0xff,
+    0xff, 0x12, 0x40, 0x1b,
+    0x00, 0x00, 0x00, 0x00,
+    0x00, 0x00, 0x00, 0x00,
+    0xff, 0xff, 0xff, 0xff
+};
+

是否有這一段. 的確是有的
