net: erspan: fix erspan config overwrite
When an erspan tunnel device receives an erpsan packet with different tunnel metadata (ex: version, index, hwid, direction), existing code overwrites the tunnel device's erspan configuration with the received packet's metadata. The patch fixes it. Fixes: 1a66a836da63 ("gre: add collect_md mode to ERSPAN tunnel") Fixes: f551c91de262 ("net: erspan: introduce erspan v2 for ip_gre") Fixes: ef7baf5e083c ("ip6_gre: add ip6 erspan collect_md mode") Fixes: 94d7d8f29287 ("ip6_gre: add erspan v2 support") Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
