The tests use the tc pedit action to modify the IPv4 source address
("pedit ex munge ip src set"), but the IP header checksum is not
recalculated after the modification. As a result, the modified packet
fails sanity checks in br_netfilter after bridging and is dropped,
which causes the test to fail.
Fix this by ensuring net.bridge.bridge-nf-call-iptables is set to 0
during the test execution. This prevents the bridge from passing
L2 traffic to netfilter, bypassing the checksum validation that
causes the test failure.

In a future patch, mlxsw will start adding RIFs to uppers of front panel
port netdevices, if they have an IP address.
At the time that the front panel port is enslaved to the bridge, the bridge
MAC address does not have the same prefix as other interfaces in the
system. On Nvidia Spectrum-1 machines all the RIFs have to have the same
38-bit MAC address prefix. Since the bridge does not obey this limitation,
the RIF cannot be created, and the enslavement attempt is vetoed on the
grounds of the configuration not being offloadable.
The selftest itself however checks operation of pedit on IPv4 and IPv6
dsfield and its parts. The bridge thus does not need to participate in
routing traffic and the IP address or the RIF are irrelevant.
Fix by disabling automatic IPv6 address generation for the HW-offloaded
bridge in this selftest, thus exempting it from mlxsw router attention.
Since the bridge is only used for L2 forwarding, this change should not
hinder usefulness of this selftest for testing SW datapath or HW datapaths
in other devices.

Several tests do not set some ports down as part of their cleanup(),
resulting in IPv6 link-local addresses and associated routes not being
deleted.
These leaks were found using a BPF tool that monitors ASIC resources.
Solve this by setting the ports down at the end of the tests.

A missing stats_update callback was recently added to act_pedit. Now that
iproute2 supports JSON dumping for pedit, extend the pedit_dsfield selftest
with a check that would have caught the fact that the callback was missing.

Add a test that runs packets with dsfield set, and test that pedit adjusts
the DSCP or ECN parts or the whole field.
