Applied to dpdk-next-net/main, thanks.


Patch title and commit log updated as following while merging:
```
ethdev: fix uninitialised representor devargs

rte_eth_devargs_parse() stops initialising eth_devargs variable to zero,
which causes regression in ixgbe PCI probe.

Restore the memset for fix.

As the listed commit introduces a new argument: nb_da, the memset
takes it into account.

Fixes: 9a9eb104edf6 ("ethdev: parse multiple representor devargs")
