- IPv6 link local table is a per-SW interface array of IPv6 unicast FIBs - the per-interface ocst is sizeof(fib_table_t) which is small, w.r.t. the cost of an interface - FE80::/10 in the 'global' table points to a DPO that performs a lookup in the input interface's LL fib.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko6-36/+192
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.
