SRES is self-cleared bit, but REG_MICFIL_CTRL1 is defined as non volatile register, it still remain in regmap cache after set, then every update of REG_MICFIL_CTRL1, software reset happens. to avoid this, clear it explicitly.

There may be failure when start 1 channel recording after 8 channels recording. The reason is that the CHnF flags are not cleared successfully by software reset.
This issue is triggerred by the change of clearing software reset bit.
CHnF flags are write 1 clear bits. Clear them by force write.

Microchip USB Analyzer can activate the internal termination resistors by setting the "termination" option ON, or OFF to to deactivate them. As I've observed, both with my oscilloscope and captured USB packets below, you must send "0" to turn it ON, and "1" to turn it OFF.
From the schematics in the user's guide, I can confirm that you must drive the CAN_RES signal LOW "0" to activate the resistors.
Reverse the argument value of usb_msg.termination to fix this.
These are the two commands sequence, ON then OFF.

When the name_assign_type attribute was introduced (commit 685343fc3ba6, "net: add name_assign_type netdev attribute"), the loopback device was explicitly mentioned as one which would make use of NET_NAME_PREDICTABLE:
The name_assign_type attribute gives hints where the interface name of a given net-device comes from. These values are currently defined: ... NET_NAME_PREDICTABLE: The ifname has been assigned by the kernel in a predictable way that is guaranteed to avoid reuse and always be the same for a given device. Examples include statically created devices like the loopback device [...]
Switch to that so that reading /sys/class/net/lo/name_assign_type produces something sensible instead of returning -EINVAL.
