bouyer | Just skipping sunxi_can_rx_intr() if the DATA_OR flag is set isn't enough
to properly recover from overrrun in all case. So go the linux way and reset
the hardware.
Don't write SUNXI_CAN_INT_RX_FLAG to SUNXI_CAN_INT_REG, this could race
with hardware and clear the interrupt while there are new packets received.
SUNXI_CAN_INT_RX_FLAG clears automatically when all pending packets have been
read, so when no more packets are pending just read SUNXI_CAN_INT_REG again
and process other interrupts, if any (or RX if there are new packets pending).
With this change it seems I get overruns less often in my use case.

bouyer | Don't process RX if SUNXI_CAN_INT_DATA_OR is pending. Seems to fix occasional
RX stalls

thorpej | Eliminate use of IFF_OACTIVE.

thorpej | Rename of_match_compat_data() to of_compatible_match(). Similarly,
rename of_search_compatible() to of_compatible_lookup().
Standardize on of_compatible_match() for driver matching, and adapt
all call sites.

thorpej | Use DEVICE_COMPAT_EOL.
|
| 1.6 |
| 25-Jan-2021 |
thorpej | Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.
|
| 1.5 |
| 18-Jan-2021 |
thorpej | Remove "struct of_compat_data" and replace its usage with
"struct device_compatible_entry"; they are ABI-compatible.
Fix several "loses const qualifier" bugs encountered during
this conversion.

sunxi_can_rx_intr to prevent double count. OK'd by bouyer@.
if_percpuq(9) automatically increments if_ipackets, so don't increment it in
the driver itself to prevent double count.
