netfilter: nf_defrag_ipv6: allow nf_conntrack_frag6_high_thresh increases
Currently, net.netfilter.nf_conntrack_frag6_high_thresh can only be lowered.
I found this issue while investigating a probable kernel issue
causing flakes in tools/testing/selftests/net/ip_defrag.sh
In particular, these sysctl changes were ignored:
ip netns exec "${NETNS}" sysctl -w net.netfilter.nf_conntrack_frag6_high_thresh=9000000 >/dev/null 2>&1
ip netns exec "${NETNS}" sysctl -w net.netfilter.nf_conntrack_frag6_low_thresh=7000000 >/dev/null 2>&1
This change is inline with commit 836196239298 ("net/ipfrag: let ip[6]frag_high_thresh
in ns be higher than in init_net")
Fixes: 8db3d41569bb ("netfilter: nf_defrag_ipv6: use net_generic infra")
