Version 1.11
============

New minor release, created on 11th May 2023. Milestone: :github-fw-milestone:`Release 1.11 <12>`

Tested mainly with Vivado 2019.2 and 2020.2.

Contains Ethernet-based example designs for:

- Xilinx KC705 eval board
- Xilinx KCU105 eval board
- Xilinx VCU118 eval board
- Xilinx ZCU102 eval board
- PC053a

And PCIe-based example designs for:

- HiTech Global K800
- Xilinx VCU118 eval board


Core
----

**Backward-incompatible changes**

* ``ipbus_ctrl``: Added support for DHCP with static reservation in the DHCP server [:github-fw-issue:`212`]

  * Note: The IP address must be a static reservation in the DHCP server as the firmware does not implement DHCP renewal
  * Added generic ``DHCP_RARP`` (defaults to ``0``, i.e. RARP)
  * Replaced generic ``IPBUSPORT`` with port ``ipbus_port``
  * Replaced port ``RARP_SELECT`` with port ``IPAM_SELECT`` (same function as before, but renamed to reflect that now can choose a different IPAM implementation)
  * Added 3 output ports: ``actual_mac_addr``, ``actual_ip_addr`` and ``got_ip_addr``

**Improvements (backward-compatible)**

* PCIe interfaces (``ipbus_pcie``): Add CPLL-based version of the XDMA interface [:github-fw-issue:`216`]
* PCIe interfaces (``ipbus_pcie``): Add support for setting PCI identifiers using generics  [:github-fw-issue:`204`]

  * New generics: ``G_PCI_VENDOR_ID``, ``G_PCI_DEVICE_ID``, ``G_PCI_REVISION_ID``, ``G_PCI_SUBSYSTEM_VENDOR_ID``, ``G_PCI_SUBSYSTEM_ID`` (default values match existing hardcoded values).


**Bugfixes**

* Updated IP checksum calculation to be compliant with RFC 1624 [:github-fw-issue:`210`]


Slaves
------

**Improvements**

* Added ``ipbus_freq_ctr_adv`` - a new frequency measurement entity, which measures the frequency using a dedicated reference clock (since the IPbus clock isn't always precise, e.g. if derived from the PCIe clock) [:github-fw-issue:`219`]
* ``ipbus_syncreg_v``: Added protections against race condition that manifests in rare circumstances (enabled by setting the ``ULTRA_SAFE`` generic to ``true``) [:github-fw-issue:`189`]


Boards, example designs and utilities
-------------------------------------

**Bugfixes**

* K800 (xdma bypass): Fixed build error (signal width mismatch) [:github-fw-issue:`205`]
* VCU118 (SGMII): Fixed termination settings of clock pins [:github-fw-issue:`211`]
