Bridge, promiscous mode andCPM2

Bridge, promiscous mode andCPM2

[alebas]

Hi,

I would need confirmation on this.

As long as I have seen, bridge's stuff in kernel sets promiscous mode by using
dev_set_promiscuity, which arrives in the execution of fcc_enet's
set_multicast_list.

But this function is not developed, so the promiscous mode is never set in the
FCC Ethernet Mode Register.

Am I right? By now, I only needs the promiscous mode, so, could it be a solution
to implement only this functionality in the set_multicast_list function? Do I
need to consider anything else?

Best regards

Alexandre Bastos

Hi

Assuming CPM2 =3D> 82xx or 85xx CPU.

In the old 8260_io/fcc_enet.c	the set_multicast_list=20
function is present, bu has an early return nine lines=20
in. If you delete that return, promiscous mode works great.

I have no idea who or why that early return was put in,=20
but it does disable multicast and promiscous mode=20
on the FCC ethernets.

Yes.

Because I never wrote (or lifted from somewhere else)
the function to run the CRC generator for creating the
multicast filters (the CPM1 on 8xx has hardware support
for this).  I left the function there as a  place holder to get
promiscuous mode, and someone did finish that function.
It should be in one of the several kernel source trees......
If not, I'll try to find the patch and do it again.

Thanks (After some days of holydays).

Now, promiscous mode works fine, so board is bridging ok.

Best regards,

Alex

So,

Is this patch available? Will it be available soon or applied to any ppc
kernel tree?
This is in my to-do list for the near future, so it would be very helpful if
this were already done.

Best regards,

Alex
