known issues

• IPv6 flow director is not well-supported by ixgbe driver, only one local ip can be set in signature mode.
• IPv6 snat forwarding has not been tested yet.
• IPv6 tunnel device is not supported.
• IPv6 uoa.ko is not supported.
• Only one slave is slected in bonding mode 4, and cannot perform failover.
• Dpip cannot set nic link down.
• SNAT forwarding cannot ping if packets come from tunnel device and rss is set to 'ip' mode.
• Synproxy consumes too many mbufs when network between dpvs and rs is slow.
• Time consumed by each loop is not fairly equal, long lcore loop happens sometimes and may lead to nic buffer overflow, msg timeout ...
• Dpvs timer does not work properly when timer wheel carry-in happens.
• Packet capture is not well supported.
• Session sharing is not supported.

Release v1.6.1

• sched: consistent hash
• uoa support to get UDP client IP/port.
• integration with DPDK 17.1
• neigh state and confirm.
• more RSS mode
• performance optimization for blacklist, neighbour, etc.
• doc update and VM support.
• bug fix:
  • timer: self-contained timer frees itself in handler
  • dpip: link show issues with
  • keepalived fixes.
  • other bug fixings.
