[dpdk-dev] [PATCH v2] net/qede: fix regression introduced by b10231aed1ed

[Igor Russkikh]

> When calling rte_eth_promiscuous_enable(port_id) followed by
> rte_eth_allmulticast_enable(port_id), the port is not in promisc mode
> anymore. This patch ensures that promisc mode takes precedence over
> allmulticast mode fixing the regression introduced by b10231aed1ed.

Hi Balazs, thanks for posting!

I think we need Fixes tag here.

Devendra, could you please check if thats enough? May be we should consider
more of internal states here? What if we'll do promisc_disable() after that?
Will allmulti state persist?
