void rte_pktmbuf_dump ( FILE * f, const struct rte_mbuf * m, unsigned dump_len ) Dump an mbuf structure to the console. Append len bytes to an mbuf and return a pointer to the start address of the added data. If there is not enough headroom in the first segment, the function will return NULL, without modifying the mbuf. Right now, not supported: attachment for already indirect mbuf (e.g. - mi has to be direct). Dpdk Mempool

Since the freeze happens during extended periods of time with the screen saver running, I thought maybe I should try to stop the screen saver.About 2 weeks ago, I went to Then updates pkt_len and nb_segs of the "clone" packet mbuf to match values from the original packet mbuf.

How much is "enough" is going to depend heavily on what you're trying to accomplish. -- Matt Laswell infinite io, inc. It is used for outer packet for tunneling cases, and does not contain any extension header. Parameters mThe packet mbuf. Parameters mThe packet mbuf to be freed.

Examples: tep_termination/vxlan_setup.c. Each segment is added back into its original mempool. Parameters mdThe pointer to the mbuf. Parameters miThe indirect packet mbuf.
