The intel 82599 NIC connected server(windows server 2008) via FCoE.When I runned read IO,it is work properly .But When I write IO with block size 1M,it will loss packets.
ethtool -S eth5 statistic shows:
The flow control works properly and no packets dropped.
The flow control seems does not work properly and many packets droppeed. Is the link partner not honoring the flow control packets!
windows server 2008 FCoE configuration box:
DCBx Version:IEEE 802.1Qaz
Priority Group:Feature not present in peer TLV
Priority Flow Control:Operational
FCoE Status:Feature not present in peer TLV
Why is there differerent between read and wirte in the same environment?
What is the meanning of "tx_flow_control_xon"?
Appreciate your answer
