Shannon Nelson a35c9543cc ixgbe: allow IPsec Tx offload in VEPA mode 
[ Upstream commit 7fa57ca443 ]

When it's possible that the PF might end up trying to send a
packet to one of its own VFs, we have to forbid IPsec offload
because the device drops the packets into a black hole.
See commit 47b6f50077 ("ixgbe: disallow IPsec Tx offload
when in SR-IOV mode") for more info.

This really is only necessary when the device is in the default
VEB mode.  If instead the device is running in VEPA mode,
the packets will go through the encryption engine and out the
MAC/PHY as normal, and get "hairpinned" as needed by the switch.

So let's not block IPsec offload when in VEPA mode.  To get
there with the ixgbe device, use the handy 'bridge' command:
	bridge link set dev eth1 hwmode vepa

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.
