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.

This patch is to let it always do CRC checksum in sctp_gso_segment() by removing CRC flag from the dev features in gre_gso_segment() for SCTP over GRE, just as it does in Commit 527beb8e ("udp: support sctp over udp in skb_udp_tunnel_segment") for SCTP over UDP. It could set csum/csum_start in GSO CB properly in sctp_gso_segment() after that commit, so it would do checksum with gso_make_checksum() in gre_gso_segment(), and Commit 622e32b7 ("net: gre: recompute gre csum for sctp over gre tunnels") can be reverted now. Note that when need_csum is false, we can still leave CRC checksum of SCTP to HW by not clearing this CRC flag if it's supported, as Jakub and Alex noticed. v1->v2: - improve the changelog. - fix "rev xmas tree" in varibles declaration. v2->v3: - remove CRC flag from dev features only when need_csum is true.
