reading and writing SDO's from userspace while an EoE interface is up (but
otherwise unused) occasionally failed with:
Failed to execute SDO upload: Input/output error
EtherCAT: Requesting master 0...
EtherCAT: Successfully requested master 0.
EtherCAT ERROR 0-0: Mailbox error response received - Unknown error reply code
EtherCAT WARNING 0-0: Invalid mailbox response for eoe0s0.
EtherCAT ERROR 0-1: Mailbox error response received - Unknown error reply code
EtherCAT WARNING 0-1: Invalid mailbox response for eoe0s1.
EtherCAT WARNING 0-2: Other mailbox protocol response for eoe0s2.
EtherCAT ERROR 0-2: Reception of CoE upload response failed: No response.
EtherCAT ERROR 0-2: Failed to process SDO request.
EtherCAT 0: Releasing master...
EtherCAT 0: Released.
Skimming the documentation suggests using ecrt_master_callbacks() but it isn't
provided in userspace.
How is this supposed to work?
