-* net: The Ethernet address and header definitions will change
- attributes. The Ethernet address struct will no longer be marked as
- packed since the packed attribute is meaningless on a byte
- array. The Ethernet header will be marked as aligned on a 2-byte
- boundary and will no longer have the packed attribute. This allows
- for efficient access on CPU architectures where unaligned access is
- expensive. These changes should not impact normal usage because drivers
- naturally align the Ethernet header on receive and all known
- encapsulations preserve the alignment of the header.
+* igb_uio: In the view of reducing the kernel dependency from the main tree,
+ as a first step, the Technical Board decided to move ``igb_uio``
+ kernel module to the dpdk-kmods repository in the /linux/igb_uio/ directory
+ in 20.11.
+ Minutes of Technical Board Meeting of `2019-11-06
+ <https://mails.dpdk.org/archives/dev/2019-November/151763.html>`_.

+* lib: will fix extending some enum/define breaking the ABI. There are multiple
+ samples in DPDK that enum/define terminated with a ``.*MAX.*`` value which is
+ used by iterators, and arrays holding these values are sized with this
+ ``.*MAX.*`` value. So extending this enum/define increases the ``.*MAX.*``
+ value which increases the size of the array and depending on how/where the
+ array is used this may break the ABI.
+ ``RTE_ETH_FLOW_MAX`` is one sample of the mentioned case, adding a new flow
+ type will break the ABI because of ``flex_mask[RTE_ETH_FLOW_MAX]`` array
+ usage in following public struct hierarchy:
+ ``rte_eth_fdir_flex_conf -> rte_fdir_conf -> rte_eth_conf (in the middle)``.
+ Need to identify this kind of usages and fix in 20.11, otherwise this blocks
+ us extending existing enum/define.
+ One solution can be using a fixed size array instead of ``.*MAX.*`` value.
