No, that's just standard setup stuff for MSIX.

Hi, a question for jfv@ or whoever else is familiar with the ixgbe
driver - I am looking at a system where the adapter reports a large
number of ierrors that I traced to this stat. What does this mean?
Intuitively it seems like the receive ring isn't being drained fast
enough but wanted to confirm
This is 'missed packet count', the index has actually been misinterpreted
in the
code for a while, it was mistakenly associated with queues, but its really
per
packet buffer, and there are only more than one when there are multiple
traffic
classes (ala DCB). Even so, only MPC(0) should get
While we're on the subject, I've had some confusion for some time now:

This means the on-card FIFO, i.e. the fixed-size FIFO that is

into 3 parts: TX, RX, and FDIR (flow director).
Jack, does the sw driver control in any way the partitioning of the
FIFO? I guess enabling 2 hw queues splits the FIFO in half. But
otherwise does the driver control this in

Juli is correct, the FIFO is not partitioned by the driver queues as they
exist in the current driver, its only seperated into the 3 parts I
