Currently when a GRO packet is assembled by HW, the checksum is modified to reflect the entire packet by HW and skb->ip_summed is set to CHECKSUM_UNNECESSARY, which is not compliant with SW GRO. This patch sets up skb's network and transport header, sets the GRO packet's checksum according to pseudo header and set the skb->ip_summed to CHECKSUM_PARTIAL. This patch also use gso_size to distinguish GRO packet from normal packet, use eth_type_vlan to check the VLAN type and set the SKB_GSO_TCP_FIXEDID according to BD info during HW GRO info processing.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
