Subject: inet: frags: refactor lowpan_net_frag_init()
X-Git-Tag: v4.9.134~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1b363f81f38f28bd69ec90837da0f65161f36325;p=platform%2Fkernel%2Flinux-amlogic.git

inet: frags: refactor lowpan_net_frag_init()

We want to call lowpan_net_frag_init() earlier.
Similar to commit "inet: frags: refactor ipv6_frag_init()"

This is a prereq to "inet: frags: use rhashtables for reassembly units"
