19e2c7ac01 tests: remove decorator tag_fixme_ubuntu2204
Type: test

There is no need to use the tag_fixme_ubuntu2204 decorator.
All tests that previously used it are now stable. The neighbor test
has been moved to the extended suite because it is not related to the
type of operating system.

e4238aa34f ethernet: check destination mac for L3 in ethernet-input node
When the NIC does not support mac filter, we rely on ethernet-input
node to do the destination mac check, ie, when the interface is in L3,
the mac address for the packet must be the mac address of the
interface where the packet arrives. This works fine in ethernet-input
node when all packets in the frame might have different interfaces, ie,
ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is not set in the frame. However,
when all packets are having the same interface,
ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is set, ethernet-input node goes
through the optimized routine eth_input_single_int -> eth_input_process_frame.
That is where dmac check has a bug when all packets in the frame are
either, ip4, ip6, or mpls without vlan tags. Because without vlan tags,
the code handles all packets in fast path and ignores dmac check.
With vlan tags, the code goes to slow path where dmac check is handled
properly.

The fix is to check if we have a bad dmac in the fast path and force the
code to go to slow path which will handle dmac check properly.

Also do a wholesale correction on all the testcases which do not use
the proper dmac when sending L3 packets.

9e5694b405 fib: only update glean for interface if necessary
Type: improvement

If an interface address is added, the glean adjacency for it's covering
prefix is updated with that address. In the case of multiple addresses
within the same prefix being added, the most recently added one will end
up being used as the sender protocol address for ARP requests.

Similar behavior occurs when an interface address is deleted. The glean
adjacency is updated to some appropriate entry under it's covering
prefix. If there were multiple interface addresses configured, we may
update the address on the adjacency even though the address currently in
use is not the one being deleted.

Add a new value PROVIDES_GLEAN to fib_entry_src_flag_t. The flag
identifies whether a source interface entry is being used as the address
for the glean adjacency for the covering prefix.

Update logic so that the glean is only updated on adding an interface
address if there is not already a sibling entry in use which has the
flag set. Also, only update the glean on deleting an interface address
if the address being deleted has the flag set.

Also update unit test which validates expected behavior in the case
where multiple addresses within a prefix are configured on an interface.

8a92b68bc8 ethernet: run callbacks for subifs too when mac changes
When MAC address changes for an interface, address change callbacks are
executed for it. In turn adjacencies register a callback for MAC address
changes to be able to update their rewrite strings accordingly.

Subinterfaces inherit MAC address from the parent interface. When MAC
address of the parent interface changes, it also implies MAC address
change for its subinterfaces. The problem is that this is currently not
considered when address change callbacks are executed. After MAC address
change on the parent interface, packets sent from subinterfaces might
have wrong source MAC address as the result of stale adjacencies. For
example, ARP messages might be sent with the wrong (previous) MAC
address and address resolution will fail.

With this fix, when address change callbacks are executed for an
interface, they will be also executed for its subinterfaces. And
adjacencies will be able to update accordingly.

d9b0c6fbf7 tests: replace pycodestyle with black
Drop pycodestyle for code style checking in favor of black. Black is
much faster, stable PEP8 compliant code style checker offering also
automatic formatting. It aims to be very stable and produce smallest
diffs. It's used by many small and big projects.

Running checkstyle with black takes a few seconds with a terse output.
Thus, test-checkstyle-diff is no longer necessary.

Expand scope of checkstyle to all python files in the repo, replacing
test-checkstyle with checkstyle-python.

Also, fixstyle-python is now available for automatic style formatting.

Note: python virtualenv has been consolidated in test/Makefile,
test/requirements*.txt which will eventually be moved to a central
location.  This is required to simply the automated generation of
docker executor images in the CI.

ea8adf7637 ip-neighbor: Handle local MAC address change for incomplete adjacencies
Type: fix

When the local MAC address of an interface changes the rewrite strings
of all adjacency types need to be updated - this patch fixes the missing
case of incomplete adjacencies.
I moved the update of all adj types into the adj module, since if the
complete adjs were done by the ip-neighbour module and incomplete ones
by adj module, that would mean two walks of the adj DB, as it is not
possible to walk only a specific type.
UT is updated to include the missing case.

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:
