[PATCH net-next v2 0/4] bonding/balance-alb: support VMs behind bridges better

[Jarod Wilson]

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.

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.

Jarod Wilson (4):
  bonding: add pure source-mac-based tx hashing option
  bonding/balance-lb: don't rewrite bridged non-local MACs
  bonding/balance-alb: don't tx balance multicast traffic either
  bonding/balance-alb: put all slaves into promisc
