Subject: [PATCH 0/2] can: drop tx skb if the device is in listen only mode

In listen only mode, tx CAN frames can still reach the driver if
injected via the packet socket. This series add a check toward
CAN_CTRLMODE_LISTENONLY in can_dropped_invalid_skb() to discard such
skb. The first patch does some preparation work and migrates
can_dropped_invalid_skb() from skb.h to dev.h. The second and last
patch is the actual change.

Vincent Mailhol (2):
  can: move can_dropped_invalid_skb from skb.h to dev.h
  can: dev: drop tx skb if in listen only mode
