[2nd try ... 1st attempt didn't make it to netdev mailing list]
A quick google search reveals that people with this card are blacklisting it
in the initramfs and in the module blacklist based on a statement that it
is unsupported. Since the older Digium is also unsupported I'm pretty
confident that this newer card is also not supported.lspci -xxx -vv shows

On ARM, memory accesses through packed pointers behave in unexpected
ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163
for discussion.In this particular case, 32-bit I/O registers are accessed bytewise,
causing incorrect setting of the DMA address registers which in turn
leads to an error interrupt storm that brings the system to a halt.Since the mac_regs structure does not need any packing anyway, this patch
simply removes the attribute to fix the issue.Signed-off-by: Ulrich Hecht

In igmp_group_dropped() we call ip_mc_clear_src(), which resets the number
of source filters per mulitcast. However, igmp_group_dropped() is also
called on NETDEV_DOWN, NETDEV_PRE_TYPE_CHANGE and NETDEV_UNREGISTER, which
means that the group might get added back on NETDEV_UP, NETDEV_REGISTER and
NETDEV_POST_TYPE_CHANGE respectively, leaving us with broken source
filters.To fix that, we must clear the source filters only when there are no users
in the ip_mc_list, i.e. in ip_mc_dec_group() and on device destroy.Acked-by: David L Stevens

The %pK format specifier is designed to hide exposed kernel pointers,
specifically via /proc interfaces. Exposing these pointers provides an
easy target for kernel write vulnerabilities, since they reveal the
locations of writable structures containing easily triggerable function
pointers. The behavior of %pK depends on the kptr_restrict sysctl.If kptr_restrict is set to 0, no deviation from the standard %p behavior
occurs. If kptr_restrict is set to 1, the default, if the current user
(intended to be a reader via seq_printf(), etc.) does not have CAP_SYSLOG
(currently in the LSM tree), kernel pointers using %pK are printed as 0's.
If kptr_restrict is set to 2, kernel pointers using %pK are printed as
0's regardless of privileges. Replacing with 0's was chosen over the
default "(null)", which cannot be parsed by userland %p, which expects
"(nil)".The supporting code for kptr_restrict and %pK are currently in the -mm
tree. This patch converts users of %p in net/ to %pK. Cases of printing
pointers to the syslog are not covered, since this would eliminate useful
information for postmortem debugging and the reading of the syslog is
already optionally protected by the dmesg_restrict sysctl.Signed-off-by: Dan Rosenberg

While chasing a possible net_sched bug, I found that IP fragments have
litle chance to pass a congestioned SFQ qdisc :- Say SFQ qdisc is full because one flow is non responsive.
- ip_fragment() wants to send two fragments belonging to an idle flow.
- sfq_enqueue() queues first packet, but see queue limit reached :
- sfq_enqueue() drops one packet from 'big consumer', and returns
NET_XMIT_CN.
- ip_fragment() cancel remaining fragments.This patch restores fairness, making sure we return NET_XMIT_CN only if
we dropped a packet from the same flow.Signed-off-by: Eric Dumazet

Ehea will not register multicast groups in phyp if the physical
interface is in promiscuous mode. But it should register if the
logical port is in promiscuous mode, but the physical port is not.Ehea physical promiscuous mode is defined by ehea_port->promisc,
while logical port is defined by IFF_PROMISC.So currently, if the user set the interface in promiscuous mode,
IGMP will not be registred in PHYP, and PHYP will never pass
the multicast packet to the logical port, which is badSo, this patch just fixes it, assuring that we register in phyp
if the physical port is not on promiscuous mode.Signed-off-by: Breno Leitao
