[PATCH] s390: qeth network driver From: Steffen Thoss <[EMAIL PROTECTED]> From: Frank Pavlic <[EMAIL PROTECTED]> qeth network driver changes: - Improve performance by omitting svs. - Use function callback mechanism to set layer 2 parameters when getting a reply for a Layer 2 command. - dev->hard_header must not be NULL when fake_ll is no set since IPv6 and Layer2 needs the default function set by network stack. - ping6 works now when running in layer 2 mode. - Save original dev->hard_header to restore it when the user doesn't want to use fake_ll anymore. - Fake ethernet header in outgoing packets. This currently works only if qeth is compiled without ipv6 support. - Add more debug information in case of failures in qeth_set_offline. - Using fake_ll with HiperSockets devices results in misaligned ip packets and thus no traffic over HiperSockets. - Start qeth_remove_device only after the qeth recovery completed.

It would be nice if this stuff was CC'd to the network, and network driver maintainers.
Two immediate concerns I have are,
* saving and restoring dev->hard_header is more than a little bit of a hack
* overall, I'm not so sure IPv6 support should be conditionalized on anything but CONFIG_IPV6. Though S/390 and qeth are certainly unusual cases, none of the other net drivers in the kernel require a special config option to enable IPv6 support.
