selftests: xsk: Disable IPv6 on VETH1
[ Upstream commit f2b50f17268390567bc0e95642170d88f336c8f4 ]
This change fixes flakiness in the BIDIRECTIONAL test:
# [is_pkt_valid] expected length [60], got length [90]
not ok 1 FAIL: SKB BUSY-POLL BIDIRECTIONAL
When IPv6 is enabled, the interface will periodically send MLDv1 and
MLDv2 packets. These packets can cause the BIDIRECTIONAL test to fail
since it uses VETH0 for RX.
For other tests, this was not a problem since they only receive on VETH1
and IPv6 was already disabled on VETH0.
