Re: [dpdk-dev] Accessing "device_id" from "rte_pci_device"

["santhosh K.S" <santhoshachar08@gmail.com>]

Hi  Rami Rosen, et al,

Thanks for the response. Yes I can see in the code that rte_device struct
is part of rte_eth_dev_info. I tried to apply the patch you pointed o
<http://patchwork.dpdk.org/patch/37654/>n 17.11.3. But it failed at many
places. We don't want to migrate to 18.05 as it is not a stable release.
I've been asked to migrate to a stable version only. I also noticed from
the release note
<https://doc.dpdk.org/guides-18.05/rel_notes/release_18_05.html> that
*rte_ctrlmbuf_init()
API *is deprecated in 18.05. Which results in breaking our code, which
means more re-work; which we are trying our best to avoid at this point in
time. Hence We are not interested in migrating to 18.05. Can you please
suggest a safer alternative patch, which I can use to get around this
problem?

Best Regards,
Santhosh K S
