Subject: flow_dissect: call init_default_flow_dissectors() earlier
From: Eric Dumazet <[email protected]>
commit c9b8af1330198ae241cd545e1f040019010d44d9 upstream.
Andre Noll reported panics after my recent fix (commit 34fad54c2537 "net: __skb_flow_dissect() must cap its return value")
After some more headaches, Alexander root caused the problem to init_default_flow_dissectors() being called too late, in case a network driver like IGB is not a module and receives DHCP message very early.
Fix is to call init_default_flow_dissectors() much earlier, as it is a core infrastructure and does not depend on another kernel service.
