Subject: [dpdk-dev] [PATCH 19.11 V2 01/12] net/ixgbevf: fix stats update after a PF reset
Date: Wed,  7 Aug 2019 17:09:10 +0200
Message-ID: <af1275dfaf535564577a57bf783fba80df3f40ef.1565190405.git.thierry.herbelot@6wind.com> (raw)
In-Reply-To: <cover.1565190405.git.thierry.herbelot@6wind.com>
In-Reply-To: <cover.1565190405.git.thierry.herbelot@6wind.com>

From: Guo Fengtian <fengtian.guo@6wind.com>

When PF is set down, in VF, the value of stats register is zero.
So only increase stats when it's non zero.

Fixes: af75078fece3 ('first public release')
