[dpdk-dev] [PATCH 1/2] net/ice/base: get PF ID of VF's parent

[dpdk-dev] [PATCH 1/2] net/ice/base: get PF ID of VF's parent

[dapengx.yu]

From: Dapeng Yu <dapengx.yu@intel.com>

In original implementation, when one or more VFs are created, and VF0
is used as DCF, there is no way to get the physical function ID of their
parent adapter via VF0. The physical function ID is critical for
initializing ACL feature, if wrong physical function ID is used, the ACL
cannot be initialized successfully, and the ACL rule cannot take effect.

This patch makes VF able to get its parent's physical function ID.

[dpdk-dev] [PATCH 2/2] net/ice: get PF ID of VF's parent

[dapengx.yu]

From: Dapeng Yu <dapengx.yu@intel.com>

In original implementation, when DCF is initialized, the physical
function ID of its parent adapter is not set correctly. Its initial
value is always zero, even if DCF is created on 1# physical function
and, further, causes ACL to initialize wrongly. Finally, the ACL flow
rule cannot take effect if it is created via VF0 of physical
function 1#.

This patch makes VF able to get its parent's physical function ID.

[dpdk-dev] [PATCH v2] net/ice/base: get PF ID of VF's parent

[dapengx.yu]

From: Dapeng Yu <dapengx.yu@intel.com>

In original implementation, if DCF is created on PF1, the PF ID is
still 0, but not 1. Without the right PF ID, the ACL will not work.

This patch makes VF to get its parent's physical function ID.
