mtk_star_dma_unmap_rx() should unmap the dma_addr of old skb rather than
that of new skb.
Assign new_dma_addr to desc_data.dma_addr after all handling of old skb
ends to avoid unexpected receive side error.

The value of "lmac_id" can be controlled by the user and if it is larger
then the number of bits in long then it reads outside the bitmap.
The highest valid value is less than MAX_LMAC_PER_CGX (4).

When receiver does not accept TCP Fast Open it will only ack

the data for (re)transmission in tcp_rcv_fastopen_synack().

My laptop crashes at boot, and I ran the same kernel with KASAN enabled.
Turns out the DMI addition for iwlwifi is broken (and untested?), since
it doesn't properly terminate the scan table. Ensure that we do so.

The D_CAN controller supports up to 128 messages. Until now the driver
only managed 32 messages although Sitara processors and DRA7 SOC can
handle 64.
The series was tested on a beaglebone board.
Note:
I have not changed the type of tx_field (belonging to the c_can_priv
structure) to atomic64_t
