/*
 * For all devices, three channels must be available to the driver. One
 * channel is the read channel, one is the write channel and the third
 * one is the channel used to control QDIO.
 *
 * There are several stages from the channel recognition to the running
 * network device:
 * - The channels are scanned and ordered due to the parameters (see
 *   MODULE_PARM_DESC)
 * - The card is hardsetup: this means, that the communication channels
 *   are prepared
 * - The card is softsetup: this means, that commands are issued
 *   to activate the network parameters
 * - After that, data can flow through the card (transported by QDIO)
 *
 *IPA Takeover:
 * /proc/qeth_ipa_takeover provides the possibility to add and remove
 * certain ranges of IP addresses to the driver. As soon as these
 * addresses have to be set by the driver, the driver uses the OSA
 * Address Takeover mechanism.
 * reading out of the proc-file displays the registered addresses;
 * writing into it changes the information. Only one command at one
 * time must be written into the file. Subsequent commands are ignored.
 * The following commands are available:
 * inv4
 * inv6
 * add4 <ADDR>/<mask bits>[:<interface>]
 * add6 <ADDR>/<mask bits>[:<interface>]
 * del4 <ADDR>/<mask bits>[:<interface>]
 * del6 <ADDR>/<mask bits>[:<interface>]
 * inv4 and inv6 toggle the IPA takeover behaviour for all interfaces:
 * when inv4 was input once, all addresses specified with add4 are not
 * set using the takeover mechanism, but all other IPv4 addresses are set so.
 *
 * add# adds an address range, del# deletes an address range. # corresponds
 * to the IP version (4 or 6).
 * <ADDR> is a 8 or 32byte hexadecimal view of the IP address.
 * <mask bits> specifies the number of bits which are set in the network mask.
 * <interface> is optional and specifies the interface name to which the
 * address range is bound.
 * E. g.
 *   add4 C0a80100/24
 * activates all addresses in the 192.168.10 subnet for address takeover.
 * Note, that the address is not taken over before an according ifconfig
 * is executed.
 *
 *VIPA:
 * add_vipa4 <ADDR>:<interface>
 * add_vipa6 <ADDR>:<interface>
 * del_vipa4 <ADDR>:<interface>
 * del_vipa6 <ADDR>:<interface>
 *
 * the specified address is set/unset as VIPA on the specified interface.
 * use the src_vipa package to exploit this out of arbitrary applications.
 *
 *Proxy ARP:
 *
 * add_rxip4 <ADDR>:<interface>
 * add_rxip6 <ADDR>:<interface>
 * del_rxip4 <ADDR>:<interface>
 * del_rxip6 <ADDR>:<interface>
 *
 * the specified address is set/unset as "do not fail a gratuitous ARP"
 * on the specified interface. this can be used to act as a proxy ARP.
