[dpdk-dev] SEGMENTATION FAULT in kni example : kni_free_kni() call

[Ariel Rodriguez <arodriguez@callistech.com>]

Hi, im trying the kni example. When i hit ctrl-c in the terminal  stopping
the example, the os signals  with a segmentation fault.

The issue is in this block of code:

static int kni_free_kni(uint8_t port_id) {
uint8_t i;
struct kni_port_params **p = kni_port_params_array;

if (port_id >= RTE_MAX_ETHPORTS || !p[port_id])
return -1;

-- for (i = 0; i < p[i]->nb_kni; i++) {
-- rte_kni_release(p[i]->kni[i]);
-- p[i]->kni[i] = NULL;
}
rte_eth_dev_stop(port_id);

return 0;
}


The following change fix that issue:

static int kni_free_kni(uint8_t port_id) {
uint8_t i;
struct kni_port_params **p = kni_port_params_array;

if (port_id >= RTE_MAX_ETHPORTS || !p[port_id])
return -1;

++ for (i = 0; i < p[port_id]->nb_kni; i++) {
++ rte_kni_release(p[port_id]->kni[i]);
++ p[port_id]->kni[i] = NULL;
}
rte_eth_dev_stop(port_id);

return 0;
}

Sorry for the basic of my fix ... i dont know  the correct style to report
this kind of issues... im just a user of the dpdk library ... but i meet
this bug ...
