After device recovery, only a basic set of network device features is
enabled on the device. If features like checksum offloading or TSO were
enabled by the user before the recovery, this results in a mismatch
between the network device features, that the kernel assumes to be
enabled on the device, and the features actually enabled on the device.
This patch tries to restore previously set features, that require
changes on the device, after the recovery of a device. In case of an
error, the network device's features are changed to contain only the
features that are actually turned on.

This patch introduces a common set of fix_features and set_features
functions for layer 2 and layer 3. The RX, TX and TSO offload
functionality on the OSA card is enabled using ethtool at user's

For layer 3 the RX checksum offloading is disabled at device

In layer3 mode of the qeth driver, multicast IP addresses
from struct net_device and other type of IP addresses
from other sources require mapping to the OSA-card.
This patch simplifies the IP address mapping logic, and changes imple-
mentation of ndo_set_rx_mode callback and ip notifier events.
Addresses are stored in private hashtables instead of lists now.
It allows hardware registration/removal for new/deleted multicast

In layer2 mode of the qeth driver, MAC address lists
from struct net_device require mapping to the OSA-card.
The existing implementation is inefficient for lists with
more than several MAC addresses, since for every
ndo_set_rx_mode callback it removes all MAC addresses first,
and then registers the current MAC address list.
This patch changes implementation of ndo_set_rx_mode callback
in qeth, only performing hardware registration/removal for
new/deleted addresses. To shorten lookup of MAC addresses
registered addresses are kept in a hashtable instead of a

This patch moves the hardware checksum offloading setup

If the card is not online at the moment (e.g. it is undergoing

of the hardware query operation when the card is not online.

The existing port isolation mode 'forward' will now verify that the adjacent
switch port supports the required reflective relay (RR) mode. This patch adds
the required error handling for the cases where enabling port isolation mode
'forward' can now fail.
Furthermore, once established, we never fall back from one of the port
isolation modes to a non-isolated mode without further user-interaction.
This includes cases where the isolation mode was enabled successfully, but
ceases to work e.g. due to configuration changes at the switch port.
Finally, configuring an isolation mode with the device being offline
will make onlining the device fail permanently upon errors encountered until
either errors are resolved or the isolation mode is changed by the user to a
different mode.
