[PATCH v2 0/4] can: c_can: cache frames to operate as a true FIFO

Performance tests of the c_can driver led to the patch that gives the
series its name. I also added two patches not really related to the topic
of the series.

Changes in v2:
- Move c_can_get_tx_free() from c_can_main.c to c_can.h.

Dario Binacchi (4):
  can: c_can: remove struct c_can_priv::priv field
  can: c_can: exit c_can_do_tx() early if no frames have been sent
  can: c_can: support tx ring algorithm
  can: c_can: cache frames to operate as a true FIFO
