Subject: Re: [dpdk-dev] [PATCH 02/11] net/failsafe: fix sub-device visibility
Date: Wed, 9 May 2018 14:13:20 +0200	[thread overview]
Message-ID: <20180509121320.qpoixqsoxtlcjyak@bidouze.vm.6wind.com> (raw)
In-Reply-To: <20180509094337.26112-3-thomas@monjalon.net>

I think this patch should be swapped with the next commit
"ethdev: add doxygen comments for each state",
While the comment about "DEFERRED" would be edited in this one to become:
/** The deferred state is deprecated and replaced by ownership. */
                          ^^^^^^^^^^
Otherwise I agree that the device state is not to be used anymore.
