We do count them, as errors!
This is what happens when you transmit a single CAN frame with nothing
connected: "TX errors" shoots up but "RX packets" stays zero.
This is handled not consistent in the existing CAN drivers. In flexcan
all and c_can (all but rx overflow) are counted as rx_packets and
rx_bytes. (I haven't looked at the other drivers.)
I tend to count the error frames as ordinary frames.
+1, I think we should count the packets and bytes delivered to the
network layer.
Documentation/ABI/testing/sysfs-class-net-statistics says:
What: /sys/class/<iface>/statistics/rx_packets

KernelVersion: 2.6.12

Description:
Indicates the total number of good packets received by this
network device.
I considered error frames not "good packets", but I can change that for
v3, no problem.
