Cause: rt kernels compiled without CONFIG_NETFILTER_XT_MATCH_ADDRTYPE
Consequence: Necessary module in order to add an iptables rule matching on an addrtype is not available
Fix: CONFIG_NETFILTER_XT_MATCH_ADDRTYPE=m added to config files
Result: ipt_addrtype is available and it is possible to create an iptables rule matching on addrtype

Description of problem: kernel-rt does not set CONFIG_NETFILTER_XT_MATCH_ADDRTYPE in kernel config, therefore the necessary module (ipt_addrtype) is missing from /lib/modules Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Install and boot into recent kernel-rt 2. Attempt to add a iptables rule matching on addrtype: # iptables -t nat -N blah # iptables -t nat -A PREROUTING -m addrtype --dst-type LOCAL -j blah Actual results: iptables: No chain/target/match by that name." Expected results: iptable rule should be accepted.
