Subject: netfilter: nf_defrag_ipv4: Drop redundant ip_send_check()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5f547391f5f25bb71f27860ad25bd1e4715f0752;p=openwrt%2Fstaging%2Fblogic.git

netfilter: nf_defrag_ipv4: Drop redundant ip_send_check()

Since commit 0848f6428ba3 ("inet: frags: fix defragmented packet's IP
header for af_packet"), ip_send_check() would be called twice for
defragmentation that occurs from netfilter ipv4 defrag hooks. Remove the
extra call.
