Subtrees
--------

* main
   * Some patches won't able to make -rc1, there is no list on what won't make
   * Some patches are stuck because they are waiting for response
     * All authors please response/follow your patches
   * There is a build issue needs immediate attention
     https://bugs.dpdk.org/show_bug.cgi?id=556
   * Power patches are in the queue, discussions going on
   * Thomas has priority on ehtdev patches
     * A new version of 'close()' set expected from Thomas
   * Will pull form sub-trees
   * Windows patches, most of them merged for the release
   * -rc1 most probably will be out on Monday
     * Ferruh will target to close next-net Friday evening
   * More patches can be postponed to -rc2, even library ones, need to discuss
     * Will keep release date as it is for now, will discuss it again
       around the -rc2 timeline

* next-net
   * Following ethdev patch reviews are going on, target is to get them for -rc1
     * support VLAN attributes in ETH and VLAN items
     * Rx buffer split
       * New version sent today, there is a comment from Jerin after that
         resolved we can proceed, may need a new version
     * support for hairpin between two ports
       * a new version sent this morning, Thomas is reviewing the set
     * Tunnel Offload API
       * There is an outstanding comment, need to resolve
       * Requested for a rebased version, waiting for it
     * rte_flow API thread safe
       * since patchset has both eal and ethdev patch, it will be merged to main
       * will review ethdev patch
     * ethdev cleanup patches
       * 'stop', 'close', xstats, unify returns, unify statics
         * These all target for -rc1, but will be merges as last thing to
           next-net to not cause conflict with existing ethdev patches
         * Some are waiting for new versions
   * Following ethdev patches will be postponed to next release
     * capture hardware timestamps
       * There are still issues to resolve for the patchset
       * No version received yet, too late for -rc1
     * use generic flow command to re-realize mirror rule
       * received too late (yesterday), will consider for next release
     * ethdev: add rx offload to drop error packets
       * discussions are going on, no ack by maintainers, will postpone
     * ethdev: support device reset and recovery events
       * No ack from maintainers, waiting for response
         * not clear what will happen if device can't recover
     * ethdev: add security flow item
       * There are arguments against it, will be rejected as it is
   * txgbe PMD
     * Overall looks good, planning to merge for release, minor changes requested
     * Since above ethdev cleanup patches doesn't include this PMD, it will
       conflict
       * To prevent this conflict better to close ethdev patches in -rc1, and get
         this PMD on -rc2 after rebased to latest ethdev changes.

* next-crypto
   * Akhil prepared the pull request for the -rc1
   * Two patches are not merged
     * Security one and cryptodev one
   * A cryptodev patch can be merged in -rc2, it is not ideal to merge library
     changes after -rc1, but it can be discussed case by case.

* next-eventdev
   * Jerin will prepare pull request today
   * There are two new PMDs, two DLB driver versions
     * Will wait eal and eventdev spec issues resolved in -rc1
       * eal dependency is for the new CPU instructions
         * Power changes are using those
         * Will include Ruifeng from the Arm perspective
           * The instructions are not supported by Arm, but good to check the
             architecture
         * Anyway new functions being experimental enables us fixing them later
     * Will consider PMDs for -rc2

* next-virtio
   * There is a fix in backlog can go in -rc2
   * Arm NEON patch will be postponed for next release
   * vhost add vectorized data path
     * The improvement is small, may not worth the complexity it brings
       * No go with current improvement level
   * Add async datapath to vhost sample and optimize async datapath
     * Under review
     * Will get it for -rc1 if can make on time, else will be considered
       for -rc2
   * Some vhost security issues are still stuck in the security process
     * Ferruh will be sure Maxime is involved into all, if not already

* next-net-intel
   * There is new avf shared code as a major set
   * There are other various PMD patches too, some can go in after -rc1

* next-net-mlx
   * There are new series based on new ethdev features

* next-net-mrvl
   * Ready for -rc1

* next-net-brcm
   * There will be more patches for -rc2, after ethdev features merged for -rc1
   * There are a few old patches in the backlog to take care
