I've been further educated on a use case, where a bridge sits on top of
a bond, with multiple vnetX interfaces attached to virtual machines,
also acting as ports of the bridge. Each leg of the bond goes to a
different switch, but there is NO mlag/vpc in play, the bonding driver
has to handle traffic that loops back appropriately to avoid breaking
transmission. Rather than adding some sort of mac filtering to
balance-xor mode, we switched to using balance-alb, which already does
some of this, and with the tweaks provided in this series, empirically
seems to behave as desired in actual operation.
Jarod Wilson (4):
bonding: add pure source-mac-based tx hashing option
bond_alb: don't rewrite bridged non-local MACs
bond_alb: don't tx balance multicast traffic either
bond_alb: put all slaves into promisc

v2 attempts to support srcmac-only hashing via a modparam instead of by
adding yet another hashing mode, as well as cleaning up and clarifying
commit messages.
