Update/delete of ACL lists referenced here is not permitted (assignment needs to be removed first).
Read is supported only for acls that were created and assigned by Honeycomb agent

+ (corresponding metadata is present).

+ Extensions:
+ - mixing ACEs of different type in one list is permited
+ - mixing L2/L3/L4 rules in one ACE is permited
Limitations (due to vpp limitations):
- egress rules are currently ignored (HONEYCOMB-234)
- - L4 rules are currently not supported (limited support will by provided by HONEYCOMB-218)
- - mixing L2 and L3 rules is possible only if ace-ip-version is provided
- (vpp classfier api limitation: common header fields for IP4/IP6 have different offsets)
- - L2 rules on L3 interfaces only to IP traffic (vpp classfier limitation)
+ - L4 rules support is limited (every <src,dst> port pair from provided ranges is translated to single classify
+ session; which can very slow or even crash vpp if ranges are big, see HONEYCOMB-260)
+ - ace-ip-version needs to be provided for all aces (consequence of posibility to mix ACEs of different types,
+ and vpp classfier api limitation: common header fields for IP4/IP6 have different offsets)
+ - L2 rules on L3 interfaces are applied only to IP traffic (vpp classfier limitation)
- vlan tags are supported only for sub-interfaces defined as exact-match";
