Subject: cxgb4 mbox4 errors listening to multiple multicast addresses

Hello, I'm testing some Chelsio T4 cards (T420-CR) and they seem to
reliably fail if I try to receiving multicast data on a number of
different addresses.  Actually it they fail even before any data is
sent, so it must be simply subscribing to the multicast addresses that
is the problem.  See below for an example.

$ uname -r
3.3.1

$ ethtool -i eth6
driver: cxgb4
version: 1.3.0-ko
firmware-version: 1.3.10.0, TP 0.1.7.0
bus-info: 0000:04:00.4
supports-statistics: yes
supports-test: no
supports-eeprom-access: yes
supports-register-dump: yes

I've got vlan824 configured to use eth6.  So if with iperf I can do:

$ route add -net 224.0.0.0 netmask 240.0.0.0 dev vlan824
$ for x in $(seq 1 95); do iperf -s -u -B 224.4.4.${x} -p 500${x} & done

$ dmesg | grep cxgb4

Then on a second machine, I set up the iperf client to send the
multicast data.

machine2 $ route add -net 224.0.0.0 netmask 240.0.0.0 dev vlan824
machine2 $ for x in $(seq 1 95); do iperf -u -c 224.4.4.${x} -p 500${x} -l 100 -b 10M & done

The receiver will receive some of the packets on a few of the
addresses, but most of the addresses never receive anything.  I
realize this could be because we are simply dropping packets, but even
running a single instance of the iperf client on machine2 for many of
the addresses causes no packets to be received for example:

machine2 $ iperf -u -c 224.4.4.65 -p 50065 -l 100 -b 10M

Is there any translation of those cryptic mbox 4 errors?

Thanks,
Shawn
