Subject: [dpdk-dev] [PATCH 4/4] net/bnxt: fix vfrep port add when it's endpoint interface is down
Date: Wed, 29 Jul 2020 19:34:59 +0530 [thread overview]
Message-ID: <20200729140459.5227-5-somnath.kotur@broadcom.com> (raw)
In-Reply-To: <20200729140459.5227-1-somnath.kotur@broadcom.com>
From: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>
While adding vfrep port to OVS bridge, vnic & svif information of
vfrep's endpoint(VF) would be needed to program default flow rules.
However, if the endpoint interface is down when vfrep port is added,
firmware will return invalid vnic & svif information.
This patch fixes the problem by registering to DEFAULT_VNIC_CHANGE
async event and once the async event is received, use the endpoint
information(VF's fid) to fetch it's vnic & svif information and
program the default flow rules.
Fixes: 322bd6e70272 ("net/bnxt: add port representor infrastructure")
