commit 5f78e29cee ("qeth: optimize IP handling in rx_mode callback")
restructured the internal address handling.
This work broke setting a virtual IP address.
The command
echo 10.1.1.1 > /sys/bus/ccwgroup/devices/<device>/vipa/add4
fails with file exist error even if the IP address has not
been set before.
It turned out that the search result for the IP address
search is handled incorrectly in the VIPA case.
This patch fixes the setting of an virtual IP address.

According to recent performance measurements, turning on net_device
feature NETIF_F_SG only behaves well, but turning on feature
NETIF_F_GSO shows bad results. Since the kernel activates NETIF_F_GSO
automatically as soon as the driver configures feature NETIF_F_SG, qeth
should not activate feature NETIF_F_SG per default, until the qeth
problems with NETIF_F_GSO are solved.

To reduce the need of skb_linearize() calls, gso_max_segs of qeth
net_devices had been limited according to the maximum number of qdio SBAL
elements. But a gso segment cannot be larger than the mtu-size, while an
SBAL element can contain up to 4096 bytes. The gso_max_segs limitation
limits the maximum packet size given to the qeth driver. Performance
measurements with tso-enabled qeth network interfaces and mtu-size 1500
showed, that the disadvantage of smaller packets is much more severe than
the advantage of fewer skb_linearize() calls.
This patch gets rid of the gso_max_segs limitations in the qeth driver.

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.

The function set_features is called to configure network device features
on the hardware. If errors occur, the network device features should
reflect the changed hardware state and the function should return an
error in order to notify the user.
In case of an error, the current implementation does not necessarily
save the changed hardware state in the network device features before an
error is returned.
This patch improves error handling by saving features, that could be
changed, to the network device features before returning an error. If
the device is not running, an additional check in fix_features removes
features, that require hardware changes, before they are passed to
set_features. Thus, the corresponding check was removed in set_features.

Network device features indicate the capabilities of network devices (e.g.,
TX checksum offloading and TSO) and their configuration state. Additional
network device features (vlan_features) indicate for each network device,
which capabilities can be used on VLAN devices, that are configured on the
respective base network device.
In the current qeth implementation, network device features are only set
for the base network devices and not for the VLAN devices. Thus, features
like TX checksum offloading cannot be used on VLAN devices.
This patch adds network device features to vlan_features, so they can be
used by VLAN devices.
