If I read the bug report correctly, it's not moved to lxc. Rather, KVM
is not required to reproduce it, using lxc is enough to trigger the
bug. Using KVM will of course still trigger the bug as well.

Probably because not many people use balance-rr. Mission-critical
setups would use 802.3ad (with suitable switches), while beginners
would mostly stick with active-backup.

Since the original bug report is quite old, and you're not using
ubuntu, I suggest you:
- try latest kernel, to make sure the bug still exists there (e.g.
using 4.2 from http://elrepo.org/tiki/kernel-ml)
- file a bug report to centos and/or linux kernel maintainers
