Subject: [RFC PATCH 00/24] TRILL implementation

Hi,

We have been working on a TRILL implementation in the Linux kernel for some
months now.  The code has been pushed here https://github.com/Gandi/ktrill.git
along the way.  Attached a series of patch as a first proposition.  The code is
not perfect and probably still lacks of improvements. It's a first request of
comment in order to get some feedbacks. This code has been tested for some
months now.

These patch tries to implement TRILL protocol RFC 6325.  As a First
implementation, some RFC details are still not implemented.

We still need to fix these points: 
- The use of rtnetlink instead of the actual netlink.
- BPDU handling

Also some parts may not be fully linux compliant, so we are waiting for
comments

In order to test theses patches please follow this small wiki download quagga
(userland) from here https://github.com/Gandi/quagga.git compile it using these
options ./bootstrap.sh && ./configure --localstatedir=/var/run/quagga
--enable-isisd --enable-trilld --disable-ipv6 --disable-ospfd
--disable-ospfclient --disable-ripd --disable-babeld --disable-bgpd && make &&
make install

start zebra and trilld  $ zebra -f $ZEBRA_CONF -P 2121 -u quagga -d $ trilld -f
$TRILLD_CONF -P 2021 -u quagga -d

configuration sample can be found here
https://github.com/Gandi/quagga/blob/dev_trill/zebra/zebra.conf.sample and here
https://github.com/Gandi/quagga/blob/dev_trill/isisd/trilld.conf.sample


Finally you need to correctly configure bridge port 

For access port (native frames) echo 4 >
/sys/class/net/<INTERFACE>/brport/trill_state For trunk port (trill frame and
control frames) echo 8 > /sys/class/net/<INTERFACE>/brport/trill_state 

more detail can be found here: https://github.com/Gandi/ktrill/wiki NB: for port
state github version has different flags as we did not take into consideration
all port flag when implementing it
