>
> This patchset fixes several issues found in vmxnet3 driver
> when enabling LRO offload support:
> - 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.
