In this case, I think the issue is different: wireguard does not
seem to explicitly depend on xt_hashlimit:

$ modinfo /lib/modules/4.9.0-1-ARCH/kernel/net/wireguard.ko
depends:        udp_tunnel,ip6_udp_tunnel,x_tables

$ modinfo /lib/modules/4.9.0-1-ARCH/kernel/net/netfilter/x_tables.ko.gz
description:    {ip,ip6,arp,eb}_tables backend module

$ modinfo /lib/modules/4.9.0-1-ARCH/kernel/net/netfilter/xt_hashlimit.ko.gz
alias:          ip6t_hashlimit
alias:          ipt_hashlimit
depends:        x_tables

Jason, what do you think of the github issue linked below?  Should
wireguard explicitly depend on xt_hashlimit?  How do you handle the
dependency chain on other platforms?
