> Subject: [PATCH v2] net/i40e: fix IPv4 fragment offload issue
>
> IPv4 fragment_offset mask was required to be 0 no matter what the spec value
> was. But zero mask means not caring about fragment_offset field then both
> non-frag and frag packets should hit the rule.
>
> But the actual fragment rules should be like the following:
> Only non-fragment packets can hit Rule 1:
> Rule 1: mask=0x3fff, spec=0
> Only fragment packets can hit rule 2:
> Rule 2: mask=0x3fff, spec=0x8, last=0x2000
>
> This patch allows the above rules.
