+ * 1. Create a dissect_<vendorname> function with the following prototype:
+ * dissect_foovendor(tvbuff_t *tvb, proto_tree *tree, guint8 vsif_len)
+ * 2. vsif_len will be the *entire* length of the vsif TLV (including the

+ * 3. Create a new 'case' statement in dissect_vsif, for your specific Vendor

+ * 4. In that 'case' statement you will make the following calls:
+ * (assume for this example that your vendor id is 0x000054)

+ * case VENDOR_FOOVENDOR:
