6d95f8c983 tests: fix test failure with parrallel test
Several test cases re-use the same test class name,
which leads to test error when do parrallel test with TEST_JOBS=16,

ec5371e3e3 ip: Fixes for IPv6 and MPLS fragmentation
Type: fix

- IPv6 fragmentation did not work if the packet spaneed multiple buffers, because the 'len' calculation to did max out at the size of a buffer
- IPv6 fragmentation did not work when the l2unfragmentable size was non-zero, it was not used in the correct places
- IPv6oMPLS fragmentation would fragment all IPv6, it should do so only for link local
- IPv6oMPLS should send back TooBig ICMP6 for non locally generated

5c6dd17a37 ip: rate-limit the sending of ICMP error messages
Type: improvement

For error conditions, such as TTL expired, dest unreach, etc, Rate limit the sending of ICMP error messages.
The rate limiting is done based on src,dst IP address of the received packet.
the rate limit has been chosen, somewhat arbitrarily, to be 1e-3. This is the same limit as the ARP throttling.

699bea2494 tests: Consolidate the implementations of send_and_expect_X
Type: test

there were multiple instances of send_and_expect_load_balancing

Even when periodic RAs are disabled VPP would respond to

06f328129a tests: add generalized tags for tests, use them for run-solo tests
We have accumulated several scenarios in prod or wishlists
where it would be useful to have a general infra to say yes/no
about a certain test, and potentially make decisions based on that,
for example:

- runs solo (aka 'time-dependent')
- (wishlist) part of quick smoke-test set
- (wishlist) intermittent failure unrelated to timing
- (wishlist) test broken with a multi-worker config in vpp

Refactor the current "run-solo" code to allow for this extension.

a3b7c554c6 tests: "force solo" testcase support
Some of the tests are time-sensitive, and at present require a non-trivial
modification in order to run at high concurrency.

Without these modifications, they intermittently fail, and require
the test retries.

Rather than setting them to the extended tests and forgetting
about them, put them into a "solo" set, which gets run in a
single-threaded mode after the rest of the tests are done.

Mark a few of the tests that showed errors during TEST_JOBS=48
as forced-solo.

Also, give a better diagnostic if the testcase misses a docstring
needed to represent it in the diagnostic outputs.

9db6ada779 fib: Table Replace
Type: feature

from the API doc, a table replace is:

"
    The use-case is that, for some unspecified reason, the control plane
    has a very different set of entries it wants in the table than VPP
    currently has. The CP would thus like to 'replace' VPP's current table
    only by specifying what the new set of entries shall be, i.e. it is not
    going to delete anything that already eixts.
    the CP delcartes the start of this procedure with this begin_replace
    API Call, and when it has populated all the entries it wants, it calls
    the below end_replace API. From this point on it is of coursce free
    to add and delete entries as usual.
    The underlying mechanism by which VPP implements this replace is
    purposefully left unspecified.
"

In the FIB, the algorithm is implemented using mark and sweep.

Algorithm goes:
1) replace_begin: this marks all the entries in that table as 'stale'
2) download all the entries that should be in this table
 - this clears the stale flag on those entries
3) signal the table converged: ip_table_replace_end
 - this removes all entries that are still stale

this procedure can be used when an agent first connects to VPP,
as an alternative to dump and diff state reconciliation.

097fa66b98 fib: fib api updates
Enhance the route add/del APIs to take a set of paths rather than just one.
Most unicast routing protocols calcualte all the available paths in one
run of the algorithm so updating all the paths at once is beneficial for the client.
two knobs control the behaviour:
  is_multipath - if set the the set of paths passed will be added to those
                 that already exist, otherwise the set will replace them.
  is_add - add or remove the set

is_add=0, is_multipath=1 and an empty set, results in deleting the route.

It is also considerably faster to add multiple paths at once, than one at a time:

e849865fb8 ip: reassembly-separate feature and custom code
This change is made fix a crash, because is_feature flag semantics turn
out to be different from "custom app code" semantics. Introduce a flag
which custom plugins/apps can use to instead of tying that code to
is_feature flag.
