Hello Team,
Can you help me in understanding below snippet.
I was looking at the code in bond.c:bond_compose_learning_packet( ). In
this, function choose_output_slave ( ) can return NULL. And returned
pointer is used as "*port_aux = slave->aux".
How will it work?
====================================================
static struct bond_slave *
choose_output_slave(const struct bond *bond, const struct flow *flow,
struct flow_wildcards *wc, uint16_t vlan)
{
struct bond_entry *e;
int balance;
balance = bond->balance;
if (bond->lacp_status == LACP_CONFIGURED) {
/* LACP has been configured on this bond but negotiations were
* unsuccussful. If lacp_fallback_ab is enabled use active-
* backup mode else drop all traffic. */
if (!bond->lacp_fallback_ab) {
return NULL;
}
.....
===================================================
===================================================
slave = choose_output_slave(bond, &flow, NULL, vlan);
packet = ofpbuf_new(0);
compose_rarp(packet, eth_src);
if (vlan) {
eth_push_vlan(packet, htons(ETH_TYPE_VLAN), htons(vlan));
}
*port_aux = slave->aux;
ovs_rwlock_unlock(&rwlock);
}
======================================================

Neeraj
