[PATCH 2/3] net/ixgbe: initialise nb_representor_ports value

[Declan Doherty]

Initialise rte_ethdev_args nb_representor_ports to zero to handle
the case where no devargs are passed to the IXGBE PF on
device probe, so that there is no invalid attempts to create
representor ports.

Might be a bit better:
If (pci_dev->device.devargs) { rte_eth_devargs_parse(...);...}
else memset(&eth_da, 0, sizeof(eth_da));
to be more consistent.
BTW, I think rte_eth_devargs_parse() need to add formal check for input parameters.

Ok, thanks Konstantin, that makes sense, we're working on cleaning up 
rte_eth_devargs_parse() to align with kvargs so I'll make sure to add 
those checks.

Looks good - can I just ask to move pf_ethdev definition to the top of the function?
To comply with dpdk coding style.
