Subject: [dpdk-dev] [PATCH 0/3] RFC: implement VF reset for i40e, e1000 and ixgbe
Date: Tue, 24 Oct 2017 14:16:27 +0100 [thread overview]
Message-ID: <20171024131630.16595-1-luca.boccassi@gmail.com> (raw)
From: Luca Boccassi <bluca@debian.org>
These patches were originally sent by Wenzhuo Lu:
http://dpdk.org/dev/patchwork/patch/14009/
http://dpdk.org/dev/patchwork/patch/14010/
http://dpdk.org/dev/patchwork/patch/14011/
The current rte_eth_dev_reset API does not correctly reset the VF
when the PF flaps on the host. With these patches, at least the ixgbe
driver with a X540 card (Linux kernel 4.9 on the host) appears to
work correctly.
The test is as simple ip link down/up on the host, and then check that
traffic still flows through the VF in the guest.
I am not an expert in these PMDs hence the RFC mark - I would like to
ask for feedback and help from the PMD maintainers and developers.
Thanks!
