Subject: netfilter: nf_tables_trace: fix endiness when dump chain policy
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5210d393ef84e5d2a4854671a9af2d97fd1b8dd4;p=openwrt%2Fstaging%2Fblogic.git

netfilter: nf_tables_trace: fix endiness when dump chain policy

NFTA_TRACE_POLICY attribute is big endian, but we forget to call
htonl to convert it. Fortunately, this attribute is parsed as big
endian in libnftnl.
