-----------------------+------------------------
since around r46432 (the definitive last good revision is 46425) we have
problems with macvlan.
a simple pingtest shows, that somehow packets are lost:
{{{
8: br-mastergate@NONE: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
prio state UP
link/ether 02:ff:ff:ff:00:00 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.1/16 brd 192.168.255.255 scope global br-mastergate
valid_lft forever preferred_lft forever
inet 192.168.2.1/24 brd 192.168.2.255 scope global br-mastergate
valid_lft forever preferred_lft forever
inet6 fe80::ff:ffff:feff:0/64 scope link
valid_lft forever preferred_lft forever
9: roaming1@wlan0-1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue master br-mastergate state UNKNOWN
link/ether 02:ff:ff:ff:00:00 brd ff:ff:ff:ff:ff:ff
}}}
ping a connected station works only ONCE:
{{{
root@box:~ arping -I br-mastergate 192.168.94.61
ARPING to 192.168.94.61 from 192.168.0.1 via br-mastergate
Unicast reply from 192.168.94.61 [00:21:6A:32:7C:1C] 1.810ms
}}}
(it stops here, no more output)
{{{
root@box:~ arping -I wlan0-1 192.168.94.61
ARPING to 192.168.94.61 from 10.63.2.2 via wlan0-1
Unicast reply from 192.168.94.61 [00:21:6A:32:7C:1C] 11.280ms
Unicast reply from 192.168.94.61 [00:21:6A:32:7C:1C] 3.462ms
Unicast reply from 192.168.94.61 [00:21:6A:32:7C:1C] 3.461ms
}}}
(everything fine)
{{{
root@box:~ brctl show
bridge name bridge id STP enabled interfaces
br-mastergate 7fff.02ffffff0000 no roaming1
}}}
i'am unsure how to explain better, please ask.
we tried different versions, up to r47008 - without luck.
(switching kernel to 3.18 also does not help)
what we see, is e.g. that DHCP on the bridge does not work.
here the network-config, everything is set up via uci,
no cheating or tricks:
