zdev: Add support for VNIC Characteristics
zdev: Add support for VNIC Characteristics

This patch adds support for the qeth attributes that are used to
configure VNIC Characteristics.

VNIC Characteristics and BridgePort are mutually exclusive. Thus, this
patch also adds a check function for conflicting settings to the qeth
code. Also, the output when VNIC Characteristics is active is added to
the BridgePort attribute descriptions.
