Re: [PATCH v2] ixgbe: fix multi-process support

2014-12-05 13:46, Bruce Richardson:

When using multiple processes, the TX function used in all processes
should be the same, otherwise the secondary processes cannot transmit
more than tx-ring-size - 1 packets.
To achieve this, we extract out the code to select the ixgbe TX function
to be used into a separate function inside the ixgbe driver, and call
that from a secondary process when it is attaching to an
already-configured NIC.

Testing with symmetric MP app shows that we are able to RX and TX from
both primary and secondary processes once this patch is applied.

Signed-off-by: Bruce Richardson <redacted>

----
V2 Changes:
* Moved check for primary/secondary process into set_tx_function instead
  of ixgbe_txq_vec_setup, which reduces scope of diff.
* Added/cleaned up some code comments for this change

Anyone to review this patch?

Thanks
