Hi!
The:
/usr/share/doc/netifrc-0.4.0/net.example.bz2
from the net-misc/netifrc package reads:
# Bridging (802.1d)
# For bridging support emerge net-misc/bridge-utils
# To add ports to bridge br0
#bridge_br0="eth0 eth1"
...
et cetera
...
How is this done with the bridge utility from iproute2 package is not very
clear to a non-expert. It sure is all completely different than with brctl.
Reminds me of how lots of people still prefer iptables over netfilter,
because there are good reason to do so.
It this a similar case?
While managing ones' ethernet interfaces, esp. the link and address of,
surely iproute2 package is superior than net-tools suite (expecially
the ip is superior than the ifconfig), and I mostly switched to the
better iproute2 replacements for net-tools suite, as per:
https://wiki.gentoo.org/wiki/Iproute2#iproute2_for_net-tools_swappers
-- also notice that bridge in not in the swappers there --
).
The net-tools vs. iproute2 question is solved for me in that respect.
However I can much more easily use the brctl from:
net-misc/bridge-utils
(and indeed, https://wiki.gentoo.org/wiki/Network_bridge still suggests so)
than the bridge from Iproute2 package.
Stick to bridge-utils or try the bridge from Iproute2?
And if the latter, any suggestions of a more detailed and more complete
and more user friendly tutorials?
Regards!

ip link set master br0 dev eth0

in the output of 'ip link' and 'ip addr' you'll see that eth0 shows
'master br0'

I agree it would be good if netifrc and other wiki documents converted
to iproute2 to replace brctl commands.

Sorry, that's half the story. To create the bridge:

ip link add dev br0 type bridge
You'll see the link type and all the bridge settings if you use the
'details' flag:
ip -d link

Hi, Erik!
And thanks! For this and the previous email.
But I couldn't wait long enought, and I set my bridge up with brctl.
I need it for this complex story here:
http://www.croatiafidelis.hr/foss/cap/cap-161015-qemu-devuan/
and it has already tired me very much by now (and likely that story,
somewhat Gentoo specific on my part, is not over yet).
Once bridge from iproute2 is in the netifrc documentation, and esp. in
the https://wiki.gentoo.org/wiki/Network_bridge#OpenRC I sure will use
it. I'm not very advanced to be completely at ease even with brctl :-) .
And thanks for adding it to the Wiki.

You, or someone else, should make a separate table with the comparison
of the bridge-utils (containing brctl) and iproute2's utilitiy bridge.
And then probably also the usermode-utilities (containing tunctl) and
whatever the iproute2's utilitiy is that replaces those.

The non stable netirfc supports bridge via iproute2, please see [1]

Thanks! I have taken notice.
I hope the:
/usr/share/doc/netifrc-0.4.0/net.example.bz2
of netifrc package has been updated, ot will soon be updated as well,
with tips for users who need lots of kind documentation like me ;-) !
I just looked it up, but it may be my lack of knowledge... I see brctl
there, but am unsure if iproute2's bridge is supported... Sorry!
(However, I've done my bridge configuration for now. More pressing
issues elsewhere I have...)

Esp. the one that was happening along with this discussion on
