Fix C/C++ linking problem in tool/ethercat

Continued update of master's rtdm part to xenomai 3 : ioctl context now obtained from rtdm_fd

Continued update of master's rtdm part to xenomai 3 : rtdm_user_info_t now replaced by rtdm_fd

migrate posix xenomai example to Xenomai3

migrate native xenomai example to Xenomai3

rt_dev_* has been abandonned in Xenomai3, on user side we use the regular POSIX I/O calls exposed by libcobalt

rtdm skin is equivalent to posix in Xenomai3's xeno-config. Replace XENOMAI_RTDM_*FLAGS by XENOMAI_LIB_*FLAGS to distinguish lib/example flags.

Add module installation path to configure options

Intermediate state while updating master's RTDM part to Xenomai 3

Added --with-xenomai-config to override xenomai config command, also allowing special environment variables to be passed.

Example : --with-xenomai-config="DESTDIR=/path/to/staging /path/to/xeno-config"

Fixed scheduler settings in dc_user example; use CLOCK_MONOTONIC.

Use sched_setscheduler() to set priority in user example.

Applied 0002-use-setup_timer-for-v4.15.patch from Beckhoff.

Applied CCAT patch 0001-fix-ccat-netdev-for-v4.11.patch from Beckhoff.

Ignore missing SDO entries in output.

Improved buffer overflow messages.

Support scheduler parameters in kernels >= 4.11.

Added missing configure options to documentation.

Mention igb driver in config files.

Respect bashisms.

Fixed statistics filter initialisation.

Doc.

EtherCAT functionality of igb driver.

Added clean igb driver from kernel 3.18 (no EtherCAT yet).

Do not build GPIO part of CCAT if GPIO is not configured in kernel.

Forgot Makefile.orig.

Fixed vm_fault.

Adapted vm_operations_struct for kernels >= 4.11

Fixed lib include paths

Clear unused ports; use arrows for next slaves.

Migrated user-space example to use clock_nanosleep().

Use SYNC0 + SYNC1 cycle times for cyclic start time generation.

Support changed sock_create_kern() interface from Linux 4.2.

Support changed tty_prepare_flip_string() interface from kernel 3.9.

Always clear PDO mapping in ecrt_slave_config_pdos().

devices/ccat: revert "limit rx processing to one frame per poll"

revert "limit rx processing to one frame per poll", which caused etherlab
frame timeouts in setups with more than one frame per cycle.

Always clear PDO assignment of configured sync managers.

Minor change.

Fixed fragmented SoE write request.

EoE interface configuration hints.

Included "ethercat ip" command in documentation.

Do not touch AL state of EoE slaves.

Fixed EoE data debug level 3.

Print mailbox error response data only if data_size > 0.

Fixed endianess of EoE parameters.

New alloc_netdev() API since kernel 3.17.

Prevent CCAT auto-loading.

Merged CCAT driver v0.14.

update ccat driver to v0.14
- fix ccat startup stall and 64 bit address usage
- limit rx processing to one frame per poll
- print registered gpio base to kernel log
- fix constness for *_driver objects
- refactor dma fifo initialization
- refactor rx/tx fifo code and structures

fix ccat startup stall. In case the dma memory was allocated above 4 GB limit, CCAT is unable to access it.
-> limit the dma_mask to 32-bit to omit this situation

update ccat driver to v0.13
- add driver for the SRAM function block
- add driver for the GPIO function block
- add support for multiple CCATs
- prepare support for devices without pci

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.

Add generated files to mrproper rule.

Mark download data as const.
Remove redundant code.

Fix for strings containing spaces.

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.

Add DEBUG_DATAGRAM_OVERFLOW to support ec_domain_finish datagram overflow testing

Fix datagram overflow layout issue

Remove unused variable
