Potnuri Bharat Teja 6208c2bfe2 iw_cxgb4: fix ECN check on the passive accept
[ Upstream commit 612e0486ad ]

pass_accept_req() is using the same skb for handling accept request and
sending accept reply to HW. Here req and rpl structures are pointing to
same skb->data which is over written by INIT_TP_WR() and leads to
accessing corrupt req fields in accept_cr() while checking for ECN flags.
Reordered code in accept_cr() to fetch correct req fields.

Fixes: 92e7ae7172 ("iw_cxgb4: Choose appropriate hw mtu index and ISS for iWARP connections")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
