/* Notes to Adding dissectors for Vendor specific TLVs:
|
|
* 1. Create a dissect_<vendorname> function with the following prototype:
|
|
* dissect_foovendor(tvbuff_t *tvb, proto_tree *tree, gint vsif_len)
|
|
* 2. vsif_len will be the *entire* length of the vsif TLV (including the
|
|
* Vendor ID TLV, which is 5 bytes long).
|
|
* 3. Create a new 'case' statement in dissect_vsif, for your specific Vendor
|
|
* ID.
|
|
* 4. In that 'case' statement you will make the following calls:
|
|
* (assume for this example that your vendor ID is 0x000054)
|
|
* #define VENDOR_FOOVENDOR 0x00054
|
|
* case VENDOR_FOOVENDOR:
|
|
* proto_item_append_text (it, " (foo vendor)");
|
|
* dissect_foovendor (tvb, vsif_tree, vsif_len);
|
|
* break;
|
|
* 5. Please see dissect_cisco for an example of how to do this.
