with some additional edits.

Internal SDO requests now synchronized with external requests.
Internal SDO requests are managed by master FSM and can conflict with
external requests managed by slave FSM. The internal SDO requests
includes SDO requests created by an application and external request are
typical created by EtherCAT Tool for SDO upload/download or a directory
fetch initiated with ethercat sdos command. The conflict will cause a
FPWR from an external request to be overwritten by a FPWR from an
internal SDO request (or oppersite) in the same "train" of datagrams.

Maximum length of foe filename extended to 255.

Defined list_next_entry for older kernels.

Fixed line wrapping.

Eoe mac address now derived from unique mac.
The EoE MAC address is now derived from the NIC part of the first global
unique MAC address of the linked list of available network interfaces or
otherwise the MAC address used by the EtherCAT master. The EoE MAC address
will get the format 02:NIC:NIC:NIC:RP:RP where NIC comes from the unique MAC
address (if available) and RP is the ring position of the EoE slave.

Exit properly on "restart" request to init script.
[29-init-restart]

Add generated files to mrproper rule.
[08-mrproper]

Mark download data as const.
Remove redundant code.
[07-sdo-up-download]

Fix for strings containing spaces.
[04-string-download]

Abort requests started for slave_configs that don't have any actual slaves.

When detaching a slave from a slave_config, fail any pending register requests instead of leaving them BUSY forever.

Ignore NXIO error otherwise this causes spam if network is empty or refclk not
selected yet, and syncing refclk time to master.

Do not force the DC reference clock to OP; if it is not configured it may refuse and flood the logs.

Moved userspace domain unmap to deactivate instead of release, fixing memory/ref leak.
