Message-ID: <BN8PR11MB3795E9F45A789392DFA9F1A1B8569@BN8PR11MB3795.namprd11.prod.outlook.com> (raw)

Hi Maxime and David,

I see patch " vhost: fix offload flags in Rx path " http://patches.dpdk.org/project/dpdk/patch/20210503164344.27916-4-david.marchand@redhat.com/ has been merged, and the legacy implementation is kept. Do you think we still need to fix the header check for the legacy implementation?

BRs,
Xiao
