2019-09-25api: split api generated filesOle Troan2-65/+31
Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>
2019-07-19fib: FIB Entry trackingNeale Ranns1-10/+7
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.

2019-06-26api: refactor format_vl_api_prefix_t return keysPaul Vinciguerra1-2/+2
format_vl_api_prefix_t returns a dict with keys 'address' and 'address_length', but other format_vl_api_prefix functions return a dict with 'prefix', and 'len'. Refactor all format_vl_api_prefix_t to return consistent keys 'address' and 'len'.

2018-06-11MTU: Software interface / Per-protocol MTU supportOle Troan2-4/+2
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>

2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach1-0/+3
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.
