Ronak Doshi says:

====================
vmxnet3: couple of fixes

This series fixes following issues:

Patch 1:
  This patch provides a fix to correctly report encapsulated LRO'ed
  packet.

Patch 2:
  This patch provides a fix to use correct intrConf reference.

Changes in v2:
- declare generic descriptor to be used
- remove white spaces
- remove single quote around commit reference in patch 2
- remove if check for encap_lro
====================
