Description (partial)

Symptom:
If there is situation of ICMP redirect, the packet is sent to CPU for sending ICMP-redirect message back to the host. The original packet will still go out. If this outgoing interface also has egress span source configured, then SPAN will not work.

Conditions:
Egress span source is configured on the same interface where packet goes which triggers an ICMP redirect.
