flow_dissector: fix byteorder of dissected ICMP ID
flow_dissector_key_icmp::id is of type u16 (CPU byteorder), ICMP header has its ID field in network byteorder obviously. Sparse says: net/core/flow_dissector.c:178:43: warning: restricted __be16 degrades to integer Convert ID value to CPU byteorder when storing it into flow_dissector_key_icmp. Fixes: 5dec597e5cd0 ("flow_dissector: extract more ICMP information") Signed-off-by: Alexander Lobakin <alobakin@pm.me> Signed-off-by: David S. Miller <davem@davemloft.net>
