Subject: Re: [dpdk-dev] [PATCH v2 0/7] Removal of PCI bus ABIs
Date: Fri, 8 Oct 2021 07:44:42 +0000	[thread overview]
Message-ID: <PH0PR11MB509354083131048C78CF3D45EEB29@PH0PR11MB5093.namprd11.prod.outlook.com> (raw)
In-Reply-To: <CAJFAV8z78pcBQKjCaW8pN9Yn9=gd8veUx=0kF8_08jr9O6ZRTQ@mail.gmail.com>

Thanks, I have worked with Chenbo to address this issue before.  After enable the `ALLOW_INTERNAL_API` option, it works now with SPDK.

Another issue raised by Jim Harris is that for distro packaged DPDK, since this option isn't enabled by default, this will not allow SPDK
to use the distro packaged DPDK after this release.
