Hi ,
Greetings!
This mail regarding Flow control.
We know that the 82599 supports flow control as defined in 802.3x, as well
as the specific operation of
asymmetrical flow control defined by 802.3z. The 82599 also supports
Priority Flow Control (PFC), sometimes referred to as Class Based Flow
Control or (CBFC), as part of the DCB architecture
What we would like to know is how it work if we have multiple VF's
For example if we have created 2 VF's (VF1 & VF2) belonging to the same port
1) Each of the VF is assigned to a different VM
2) Each VF is having its own MAC
3) if one of the VF1 is flooded with More traffic and ran out of
descriptor. on the other hand there is minimal traffic on VF2
4) since we ran out descriptor on VF1, how the flow control will be sent to
the PEER who is trasmitting the packet to VF1
5) Will it affect VF2 data flow.
Thanks in advance!
