The fragment packets do defrag in act_ct module. If the reassembled
packet should send out to another net device. This over mtu big packet
should be fragmented to send out. This patch add the act ct_output to

There might be some requests pending in the buffer when the
interface close sequence occurs. In some devices, these
pending requests might lead to the module not shutting down
properly when m_can_clk_stop() is called.
Therefore, move the device to init state before potentially
powering it down.

At the time of do_reset, ibmvnic tries to re-initalize the tx_pools
and rx_pools to avoid re-allocating the long term buffer. However
there is a window inside do_reset that the tx_pools and
rx_pools were freed before re-initialized making it possible to deference
null pointers.
