Netdev Support?

[civerachb-cpr]

This question relates to RobotnikAutomation/barrett_hand#18.
The short version is that I have a mobile robot that uses a Peak PCI CAN card to communicate with the drive system and BMS. I also have 2x Peak USB adapters, each connected to a Barrett hand.
The drive system and BMS both require netdev support to work; compiling the Peak driver with make NET=NO_NETDEV_SUPPORT prevents the drive system and BMS from working correctly. Compiling the Peak driver with make netdev results in the base platform being mobile and the BMS operating, but causes the driver for the hands to crash with the following error (output from the bhand_control ROS package):

Is it possible to use pcan_python with the netdev option enabled in the pcan kernel module? Or is there a combination of flags I need to use to enable both netdev and chardev simultaneously? (I don't know if that latter option is even possible.)
