netlink_delinearize: also postprocess OP_AND in set element context
|
|

Pablo reports:
|
|
|
1d03cd |
add rule netdev nt y update @macset { vlan id timeout 5s }
|
|
|
1d03cd |
|
|
|
1d03cd |
listing still shows the raw expression:
|
|
|
1d03cd |
update @macset { @ll,112,16 & 0xfff timeout 5s }
|
|
|
1d03cd |
|
|
|
1d03cd |
so also cover the 'set element' case.
