Subject: [dpdk-dev] [PATCH v4] net/ice: fix function pointer in multi-process
Date: Mon, 25 Oct 2021 13:40:29 +0800 [thread overview]
Message-ID: <20211025054029.1140977-1-dapengx.yu@intel.com> (raw)
In-Reply-To: <20211025034050.1089628-1-dapengx.yu@intel.com>
From: Dapeng Yu <dapengx.yu@intel.com>
This patch uses the index value to call the function, instead of the
function pointer assignment to save the selection of Receive Flex
Descriptor profile ID.
Otherwise the secondary process will run with wrong function address
from primary process.
Fixes: 7a340b0b4e03 ("net/ice: refactor Rx FlexiMD handling")

V2:
* Remove redundant code
V3:
* Fix incorrect switch statements in V2
V4:
* Combine similar case statements
