[PATCH RESEND 0/2] j1939: make sure that sent DAT/CTL frames are marked as TX

[Devid Antonio Filoni <devid.filoni@egluetechnologies.com>]

Hello,

If candump -x is used to dump CAN bus traffic on an interface while a J1939
socket is sending multi-packet messages, then the DAT and CTL frames
show up as RX instead of TX.

This patch series sets to generated struct sk_buff the owning struct sock
pointer so that the MSG_DONTROUTE flag can be set by recv functions.

I'm not sure that j1939_session_skb_get is needed, I think that session->sk
could be directly passed as can_skb_set_owner parameter. This patch
is based on j1939_simple_txnext function which uses j1939_session_skb_get.
I can provide an additional patch to remove the calls to
j1939_session_skb_get function if you think they are not needed.

Thank you,
Devid
