Improve feature arc order constraint specification
Add the VNET_FEATURE_ARC_ORDER macro, which allows specification of bulk order constraints. Here's an example: VNET_FEATURE_ARC_ORDER(ip4_unicast_arc_order, static) = { .arc_name = "ip4-unicast", .node_names = VNET_FEATURES ("ip4-flow-classify", "ip4-inacl", "ip4-source-check-via-rx", "ip4-source-check-via-any", "ip4-source-and-port-range-check-rx", "ip4-policer-classify", "ipsec4-input", "vpath-input-ip4", "ip4-vxlan-bypass", "ip4-not-enabled", "ip4-lookup"), }; Simply list feature nodes in the desired order, and you're done. Multiple macro instances per are are fine / expected / tested. Under the covers: generate "a before b" tuples by chain-dragging across the ordered list. No need to touch existing per-feature constraints. Fixed a long-broken "you lose!" error message. Change-Id: I259282e426fd305e22c8d65886787c41a1d348d3 Signed-off-by: Dave Barach <dave@barachs.net>
