> Subject: [dpdk-dev] [PATCH v2] ixgbe: fix multi-process support
> 
> 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 <bruce.richardson@intel.com>

> ----
> 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
