Subject: [dpdk-dev] [PATCH] net/i40e: fix offload flag checking in simple Tx datapath
Date: Tue, 27 Apr 2021 16:58:59 +0800 [thread overview]
Message-ID: <20210427085859.22376-1-alvinx.zhang@intel.com> (raw)
For Tx packets, if no other offload flag except
'PKT_TX_OUTER_IPV6, PKT_TX_OUTER_IPV4, PKT_TX_IPV6, PKT_TX_IPV4' is
set, the hardware doesn't need to do offloads for these packets.
This patch removes those previously indicated flags from the offload
flag checking in simple Tx datapath.
Fixes: 146ffa81d05e ("net/i40e: add Tx preparation for simple Tx datapath")
