62 | * MBUF | |
63 | * ==== | |
64 | * | |
65 | * #. Allocate a mbuf pool. | |
66 | * | |
67 | * - The pool contains NB_MBUF elements, where each mbuf is MBUF_SIZE | |
68 | * bytes long. | |
69 | * | |
70 | * #. Test multiple allocations of mbufs from this pool. | |
71 | * | |
72 | * - Allocate NB_MBUF and store pointers in a table. | |
73 | * - If an allocation fails, return an error. | |
74 | * - Free all these mbufs. | |
75 | * - Repeat the same test to check that mbufs were freed correctly. | |
76 | * | |
77 | * #. Test data manipulation in pktmbuf. | |
78 | * | |
79 | * - Alloc an mbuf. | |
80 | * - Append data using rte_pktmbuf_append(). | |
81 | * - Test for error in rte_pktmbuf_append() when len is too large. | |
82 | * - Trim data at the end of mbuf using rte_pktmbuf_trim(). | |
83 | * - Test for error in rte_pktmbuf_trim() when len is too large. | |
84 | * - Prepend a header using rte_pktmbuf_prepend(). | |
85 | * - Test for error in rte_pktmbuf_prepend() when len is too large. | |
86 | * - Remove data at the beginning of mbuf using rte_pktmbuf_adj(). | |
87 | * - Test for error in rte_pktmbuf_adj() when len is too large. | |
88 | * - Check that appended data is not corrupt. | |
89 | * - Free the mbuf. | |
90 | * - Between all these tests, check data_len and pkt_len, and | |
91 | * that the mbuf is contiguous. | |
92 | * - Repeat the test to check that allocation operations | |
93 | * reinitialize the mbuf correctly. | |
94 | * | |
95 | * #. Test packet cloning | |
96 | * - Clone a mbuf and verify the data | |
97 | * - Clone the cloned mbuf and verify the data | |
98 | * - Attach a mbuf to another that does not have the same priv_size. | |
