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