[dpdk-dev] [dpdk-announce] release candidate 21.11-rc1

[Thomas Monjalon]

A new DPDK release candidate is ready for testing:
	https://git.dpdk.org/dpdk/tag/?id=v21.11-rc1

There are 1171 new patches in this snapshot, big as expected.

Release notes:
	https://doc.dpdk.org/guides/rel_notes/release_21_11.html

Highlights of 21.11-rc1:
* General
	- more than 512 MSI-X interrupts
	- hugetlbfs subdirectories
	- mempool flag for non-IO usages
	- device class for DMA accelerators
	- DMA drivers for Intel DSA and IOAT
* Networking
	- MTU handling rework
	- get all MAC addresses of a port
	- RSS based on L3/L4 checksum fields
	- flow match on L2TPv2 and PPP
	- flow flex parser for custom header
	- control delivery of HW Rx metadata
	- transfer flows API rework
	- shared Rx queue
	- Windows support of Intel e1000, ixgbe and iavf
	- testpmd multi-process
	- pcapng library and dumpcap tool
* API/ABI
	- API namespace improvements (mempool, mbuf, ethdev)
	- API internals hidden (intr, ethdev, security, cryptodev, eventdev, cmdline)
	- flags check for future ABI compatibility (memzone, mbuf, mempool)

Please test and report issues on bugs.dpdk.org.
DPDK 21.11-rc2 is expected in two weeks or less.

Thank you everyone

Update the test status for Intel part. Till now dpdk21.11-rc1 test is almost finished. No critical issue is found.
One little high issue https://bugs.dpdk.org/show_bug.cgi?id=843 impacts cryptodev function and performance test.
It has patch https://git.dpdk.org/dpdk/commit/?id=eb89595d45ca268ebe6c0cb88f0ae17dba08d8f6 to fix and the patch has been merged into dpdk main.

                                - One https://bugs.dpdk.org/show_bug.cgi?id=843 about crypto performance tests for QAT are failing. Patch has been merged into dpdk main branch.
                                - One https://bugs.dpdk.org/show_bug.cgi?id=842 about FIP tests are failing. Has patch to fix and verify passed.
                *Performance test: test scenarios including Thoughput Performance /Cryptodev Latency, etc.
                        - All test done. No big performance drop. Most of performance test are blocked by Bug843.

PASS
(2)Guest with device assignment(PF) throughput testing(2M hugepage size) :
PASS
(3)Guest with device assignment(VF) throughput testing: PASS
(4)PVP (host dpdk testpmd as vswitch) 1Q: throughput testing: PASS
(5)PVP vhost-user 2Q throughput testing: PASS
(6)PVP vhost-user 1Q - cross numa node throughput testing: PASS
(7)Guest with vhost-user 2 queues throughput testing: PASS
(8)vhost-user reconnect with dpdk-client, qemu-server: qemu reconnect: PASS
(9)vhost-user reconnect with dpdk-client, qemu-server: ovs reconnect: PASS
(10)PVP 1Q live migration testing: PASS
(11)PVP 1Q post copy live migration testing: PASS
(12)PVP 1Q cross numa node live migration testing: PASS
(13)Guest with ovs+dpdk+vhost-user 1Q live migration testing: PASS
(14)Guest with ovs+dpdk+vhost-user 1Q live migration testing (2M): PASS
(15)Guest with ovs+dpdk+vhost-user 2Q live migration testing: PASS
(16)Guest with ovs+dpdk+vhost-user 4Q live migration testing: PASS
(17)Host PF + DPDK testing: PASS
