答复: [PATCH] net/iavf: eth pattern support smac and dmac match

[Dexia Li]

Hi Zhang Qi，
        When I test ovs parial offload using iavf, then found it can not 
offloaded.
        Ovs flow like this: ovs-ofctl add-flow br-int 
in_port=1,dl_type=0x0800,dl_dst=52:51:00:00:00:21,action=output:2
        I use ice 1.6.7 Pf driver.
        After modified this code, this flow can be offloaded.

Thanks
Dexia

Hi Dexia, 
        As this rely on kernel PF support.
        May I know how you prove this feature, which kernel pf driver version 
you used.
Thanks
Qi
