caif-hsi: robust frame aggregation for HSI
Implement aggregation algorithm, combining more data into a single HSI transfer. 4 different traffic categories are supported: 1. TC_PRIO_CONTROL .. TC_PRIO_MAX (CTL) 2. TC_PRIO_INTERACTIVE (VO) 3. TC_PRIO_INTERACTIVE_BULK (VI) 4. TC_PRIO_BESTEFFORT, TC_PRIO_BULK, TC_PRIO_FILLER (BEBK) Signed-off-by: Dmitry Tarnyagin <dmitry.tarnyagin@stericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>
