[ Upstream commitd9816ec74e] According to 802.1AE standard, when ES and SC flags in TCI are zero, used SCI should be the current active SC_RX. Current code uses the header MAC address. Without this patch, when ES flag is 0 (using a bridge or switch), header MAC will not fit the SCI and MACSec frames will be discarted. In order to test this issue, MACsec link should be stablished between two interfaces, setting SC and ES flags to zero and a port identifier different than one. For example, using ip macsec tools: ip link add link $ETH0 macsec0 type macsec port 11 send_sci off end_station off ip macsec add macsec0 tx sa 0 pn 2 on key 01 $ETH1_KEY ip macsec add macsec0 rx port 11 address $ETH1_MAC ip macsec add macsec0 rx port 11 address $ETH1_MAC sa 0 pn 2 on key 02 ip link set dev macsec0 up ip link add link $ETH1 macsec1 type macsec port 11 send_sci off end_station off ip macsec add macsec1 tx sa 0 pn 2 on key 01 $ETH0_KEY ip macsec add macsec1 rx port 11 address $ETH0_MAC ip macsec add macsec1 rx port 11 address $ETH0_MAC sa 0 pn 2 on key 02 ip link set dev macsec1 up Fixes:c09440f7dc("macsec: introduce IEEE 802.1AE driver") Co-developed-by: Andreu Montiel <Andreu.Montiel@technica-engineering.de> Signed-off-by: Andreu Montiel <Andreu.Montiel@technica-engineering.de> Signed-off-by: Carlos Fernandez <carlos.fernandez@technica-engineering.de> Reviewed-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: David S.

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 reStructuredText 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.
