Subject: [dpdk-dev] [PATCH 2/3] net/enic: fix speed capabilities for the new VF
Date: Wed, 30 Oct 2019 22:36:22 -0700 [thread overview]
Message-ID: <20191031053623.16185-3-hyonkim@cisco.com> (raw)
In-Reply-To: <20191031053623.16185-1-hyonkim@cisco.com>
VFs all have subsystem ID 0. VIC models with the latest VF are at
least 40G, so report that as a more reasonable speed than 10G.
Fixes: 57bb45b37bdf ("net/enic: add PCI id for new virtual function")
