Here you can define also the iface of the container:
lxc.network.name = eth0

The network.link can be br0 (actually I don't know, it could work also 
with br0:0, but i'm not sure).

In the interfaces file supposed to be this:

auto br0
iface br0 inet static
    bridge_ports eth0
    bridge_fd 0
    address 192.168.10.74
    netmask 255.255.255.248
    gateway 192.168.10.73
*    bridge_stp off
    bridge_maxwait 0*

*auto br0:0*
iface br0:0 inet static
    address 192.168.10.75
    netmask 255.255.255.248
    # not necessary gateway 192.168.10.73


So try it with these changes, I hope it will be enough and help:)
