====================
This series adds support for selecting and reporting the offloading mode
of a MACsec interface. Available modes are for now 'off' and 'phy',
'off' being the default when an interface is created. Modes are not only
'off' and 'on' as the MACsec operations can be offloaded to multiple
kinds of specialized hardware devices, at least to PHYs and Ethernet
MACs. The later isn't currently supported in the kernel though.
The first patch adds support for reporting the offloading mode currently
selected for a given MACsec interface through the `ip macsec show`
command:
# ip macsec show
18: macsec0: protect on validate strict sc off sa off encrypt on send_sci on end_station off scb off replay off
cipher suite: GCM-AES-128, using ICV length 16
TXSC: 3e5035b67c860001 on SA 0
0: PN 1, state on, key 00000000000000000000000000000000
RXSC: b4969112700f0001, state on
0: PN 1, state on, key 01000000000000000000000000000000
-> offload: phy
19: macsec1: protect on validate strict sc off sa off encrypt on send_sci on end_station off scb off replay off
cipher suite: GCM-AES-128, using ICV length 16
TXSC: 3e5035b67c880001 on SA 0
1: PN 1, state on, key 00000000000000000000000000000000
RXSC: b4969112700f0001, state on
1: PN 1, state on, key 01000000000000000000000000000000
-> offload: off
The second patch allows an user to change the offloading mode at runtime
through a new subcommand, `ip macsec offload`:
# ip macsec offload macsec0 phy
# ip macsec offload macsec0 off
If a mode isn't supported, `ip macsec offload` will report an issue
(-EOPNOTSUPP).
Giving the offloading mode when a macsec interface is created was
discussed; it is not implemented in this series. It could come later
on, when needed, as we'll still want to support updating the offloading
mode at runtime (what's implemented in this series).

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
