So the powerpc platform just honors the affinity mask, and depending on

CPUs in the affinity mask.
All interrupts by defaults are spread to all CPUs (full balancing).

Sometimes (~ 1 in 10) after suspend to disk my r8169 nic doesn't work and a
r8169: eth0: link down gets mingled up with those suspend messages.
First tests show nothing bad, so maybe this patch really helps.
Will post again, if it doesn't.

I can't get my PowerPC 83xx(eth driver ucc_qeth) board to reply on a
multcast ping:
ping -t 1 -c 2 224.0.0.1
unless I do ifconfig eth1 promisc and
echo 0 /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
I guess I am missing something, but what?

If you have icmp_echo_ignore_broadcasts set to 1, it won't respond to
multicasts. That should be all you need to do for 224.0.0.1.
Some smart switches rely on IGMP snooping to determine group membership,
and some of those don't understand IGMPv3, so if you have no v1 or v2

Ah, no problem -- even with the right keys you may sometimes get lost in
the results.
I've still some doubts about this possible enable_irq() after
free_irq(). If

Currently it does not compile because a not declared variable is used.
struct net_device_stats in driver's private struct is also unsued.
This patch uses (hopefully) the right stats.

The first three are bug fixes, followed by cleanup
and addition of new eeprom and debug interface.
Patches are against current linux-2.6 git tree which
is at pre 2.6.24 state.

Adjust ram buffer sizing calculation to make it correct on all boards
and make it like the code in sky2 driver.
