Series inet: frags: bring rhashtables to IP defrag | expand

Commit Message

Eric Dumazet March 31, 2018, 7:58 p.m. UTC 
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"
