Rather than the global promiscuous mode on all slaves, let's try to use
allmulti.
To do this, we apply the same mechanism than for promiscuous and drop in
rx_burst.
When adding a slave, we first try to use allmulti, else we try
promiscuous.
Because of this, we must be able to handle allmulti on the bonding
interface, so the associated dev_ops is added with checks on which mode
has been applied on each slave.
Rather than add a new flag in the bond private structure, we can remove
promiscuous_en since ethdev already maintains this information.
When starting the bond device, there is no promisc/allmulti re-apply
as, again, ethdev does this itself.
On reception, we must inspect if the packets are multicast or unicast
and take a decision to drop based on which mode has been enabled on the
bonding interface.
Note: in the future, if we define an API so that we can add/remove mc
addresses to a port (rather than the current global set_mc_addr_list
API), we can refine this to only register the LACP multicast mac
address.
