Qeth HiperSockets support now retries sending of packets when the
IBM System z signals a temporary resource shortage (e.g. target
buffer full). The packet is enqueued into the device queue.
After 3 times of unsuccessful send the packet is dropped.

Broadcom's phys come in two distinctly different register layouts.  For
the lack of an official term to distinguish between the two formats, we
can loosely categorize them by their fast ethernet or gigabit ethernet
transceiver description.  This patch creates the (driver-internal) Fast
Ethernet Transceiver (FET) namespace and converts the 5906 EPHY
definitions over.

This patch prevents a tx BD corruption bug by preventing the device from

When the interface is put in bridged mode, destination mac
addresses are unknown to firmware. So packets take a slow
path (lower priority) in firmware reducing performance.

Firmware can cache limited number of remote unicast mac
addresses for certain interval, if "dynamic mac learning"
mode is enabled.

Driver needs to enable this "mac learning" mode in firmware.
Currently this is done through net device class sysfs entry,
possibly this can also be done upon netlink notifications to
from bridge.
