Re: [PATCH net v2 3/3] selftests: forwarding: fix pedit tests failure with br_netfilter enabled

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, bypasing the checksum validation that

s/bypasing/bypassing/

causes the test failure.
