Commit 357d46a17e "sfc: QT202x: Remove
unreliable MMD check at initialisation" broke initialisation of the
SFE4002. efx_mdio_reset_mmd() returns a positive value rather than 0
on success. The above commit causes this value to be propagated up
by qt202x_reset_phy(), which is treated as a failure by its callers.
Change qt202x_reset_phy() to return 0 if successful.
The PCI layer treats >0 as "fail, but please call remove() anyway",
which means that unloading the driver would cause a crash. Add a
WARN_ON() on the failure path of efx_pci_probe() to provide early
warning if there are any other cases where we do this.

This is a new network driver for Micrel KSZ8841/KSZ8842 PCI Ethernet chips. The same driver can run both chips at the same time. It supports IPv4 TCP hardware checksumming and so can use scatter/gather transmission.
The KSZ8842 switch has 2 ports. Some users like to take direct control of those ports. So KSZ8842 has a multiple devices mode in which the driver creates another network device so that users can specify which port to send packets. This mode is enabled by passing the "multi_dev=1" parameter to the driver during loading.
The KSZ884X can receive huge frames with size up to 1916 bytes. To use this feature change the network device MTU from 1500 to 1898.
The KSZ884X driver has 3 packet receive processing functions for the normal mode, multiple devices mode, and huge frame mode. Those functions are identical except for more checking for the new features. In normal programming point of view the huge frame version is the one to use because it covers all the cases, but this is done for performance consideration because the target clients for the KSZ884X chips are embedded systems, which unlike desktop PC may not have powerful CPU.

A pointer to am79c961_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

This fixes a problem in the DCCP getsockopt() API: currently there is no way
for a user to a priori know the number of built-in CCIDs, other than trying
DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until
EINVAL is no longer returned.
This patch truncates the array to the user-provided length. No copy is made
when the length is <= 0.
Due to the length restriction in do_dccp_getsockopt() to sizeof(int), the
minimum array length remains 4, which is a reasonable default (only 3
CCIDs, CCID-2..4, are currently defined).

Currently we treat IGMPv3 reports as if it were an IGMPv2/v1 report.
This is broken as IGMPv3 reports are formatted differently. So we
end up suppressing a bogus multicast group (which should be harmless
as long as the leading reserved field is zero).
In fact, IGMPv3 does not allow membership report suppression so
we should simply ignore IGMPv3 membership reports as a host.
This patch does exactly that. I kept the case statement for it
so people won't accidentally add it back thinking that we overlooked
this case.
