    Intel X710 / i40en driver on vmware - any fix?


      I just received a few Dell servers to test as replacements for the vendor we currently use for vsphere.  I installed ESXi 6.5u1, patched up for spectre/meltdown so I'm now on build 7967591.  The servers are hooked into storage via multiple 10gig ethernet paths handled by dual port X710 NIC's:


      [root@vm4:~] esxcli network nic get -n vmnic0

      Almost immediately after putting any real load on them, the NIC simply stops passing traffic.  What's worse, it remains in an UP state, so vmware never tries the failover link.  Seeing this on the vmware side:


      2018-04-01T11:30:41.265Z cpu1:65925)StorageApdHandlerEv: 117: Device or filesystem with identifier [e87ff85e-cb1d8034] has exited the All Paths Down state.

      That of course lead me to the following two closed threads in this forum:





      Is it safe to assume this NIC is still broken and will never see fixes, with both sides blaming each other?  Can't say it leaves me very happy with Dell either as they knew we were doing vsphere on these, yet they still bundled them.
