> This patchset fixes several issues found in vmxnet3 driver

> - Rx offload information are not correctly gathered in
>   multisegmented packets, leading to inconsistent
>   packet type and Rx offload bits in resulting mbuf
> - MSS recovery from offload information is not done
>   thus LRO mbufs do not contain a correct tso_segsz value.
> - MSS value is not propagated by the host on some
>   hypervisor versions (6.0 for example)
> - If two small TCP segments are aggregated in a single
>   mbuf, an empty segment that only contains offload
>   information is appended to this segment, and is
>   propagated as is to the application. But if the application
>   sends back to the hypervisor a mbuf with an empty
>   segment, this mbuf is dropped by the hypervisor.
