Subject: [dpdk-dev] [PATCH v3 13/13] net/ice: redirect switch rule to new VSI
Date: Fri,  3 Apr 2020 10:43:53 +0800	[thread overview]
Message-ID: <20200403024353.24681-14-wei.zhao1@intel.com> (raw)
In-Reply-To: <20200403024353.24681-1-wei.zhao1@intel.com>

After VF reset, VF's VSI number may be changed,
the switch rule which forwards packet to the old
VSI number should be redirected to the new VSI
number.
