The workaround I've had in place for over two weeks now is to enable flow control on the Nexus 3064 on all ports that have 82599EB controllers connected. Disabling flow control on the NICs directly with ethtool works as well. No more issues.
This indicates some breakdown in the pause frame negotiation between NIC and switch, and possibly a long-standing bug in ixgbe. The kernel docs state, somewhat unclearly, that flow control is enabled. I take it this means that flow control autonegotiation is enabled. And in my case, it's clearly not working. ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
