Any plan about this patch? I have tried to build this patch, but get following errors: error: Inferred incompatible container alignments for field ingress::hdr.bridge_md.inner_vlan_id: Source unknown: alignment = 3 (little endian) Previously inferred alignments: /home/P4/fabric-tna-multi-pipe-new/p4src/include/parser.p4(61): alignment = 0 (little endian) fabric_md.inner_vlan_id = hdr.inner_vlan_tag.vlan_id; ^^^^^^^^^^^^^^^^^^^^^^^
