Subject: [dpdk-dev] [PATCH 1/4] power: fix invalid socket indicator value
Date: Thu, 14 Mar 2019 15:47:49 +0100	[thread overview]
Message-ID: <20190314144752.13812-2-marcinx.hajkowski@intel.com> (raw)
Message-ID: <20190314144749.FrEfIONwVAbZLsY3obkNXQju2EF0A5CM0UHD-HYGDis@z> (raw)
In-Reply-To: <20190314144752.13812-1-marcinx.hajkowski@intel.com>

From: Marcin Hajkowski <marcinx.hajkowski@intel.com>

Currently 0 is being used for not connected slot indication.
This is not consistent with linux doc which identifies 0 as valid
(connected) slot, thus modification was done to change it.

Fixes: cd0d5547 ("power: vm communication channels in guest")
Cc: stable@dpdk.org
