Another series with focus on the fast/normal rx/tx handlers for 802.3ad.

The first two patches make sure that the rx (resp. tx) fast and normal
handlers are equivalent.

The third one will most likely have an impact on performance which I
tried to mitigate with the last one. However, I have no benchmark to
back those patches and I did not test those thoroughly, so they are
more like RFC patches but sending anyway.

We'd better consolidate the fast queue and the normal tx burst functions
under a common inline wrapper for maintenance.

But looking closer at the bufs_slave_port_idxs[] mapping array in those
tx burst functions, its size is invalid since up to nb_bufs are handled
here.
A previous patch [1] fixed this issue for balance tx burst function
without mentionning it.

802.3ad and balance modes are functionally equivalent on transmit.
The only difference is on the slave id distribution.
Add an additional inline wrapper to consolidate even more and fix this
issue.

fast queue Rx burst function is missing checks on promisc and the
slave collecting state.
Define an inline wrapper to have a common base.

By default, the 802.3ad code enables promisc mode on all slaves.
To avoid all packets going to the application (unless the application
asked for promiscuous mode), all frames are supposed to be filtered in
the rx burst handler.

However the incriminated commit broke this because non pure ethernet
frames (basically any unicast Ether()/IP() packet) are not filtered
anymore.

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.

Hi Chas,

Reminder of this patchset, it is waiting for a long time, if there is no
objection I am for merging it.

Thanks,

It caused some additional failure in our regression testing but I haven't had time to look at it.

These patches caused some additional regressions in our local tests. I 
haven't had time to investigate it though.

OK, I was able to get a clean run for these patches through our regression
system.  I didn't see any failures with these patches applied. Consider
the following:

David Marchand (4):
   net/bonding: fix oob access in LACP mode when sending many packets
   net/bonding: fix LACP fast queue Rx handler
   net/bonding: fix unicast packets filtering when not in promisc
   net/bonding: prefer allmulti to promisc for LACP

Sorry this took so long!
