由 Tristram Ha 提交于
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.

When the fib size exceeds what can be dumped in a single skb, the dump is suspended and resumed once the last skb has been received by userspace. When the fib is changed while the dump is suspended, the walker might contain stale pointers, causing a crash when the dump is resumed.

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).

Initialize the .cmd member of various ethtool using a designated struct initializer rather.

This patchset enables the ethtool layer to program n-tuple filters to an underlying device. The idea is to allow capable hardware to have static rules applied that can assist steering flows into appropriate queues. Hardware that is known to support these types of filters today are ixgbe and niu.

Break the largish case for handling receive checksum into a separate function, and if there is a problem use dev_XXX routines to show which hardware is the problem. Turn one corner case into a BUG(). This only happens if the driver is expecting one behavior but the chip does the old behavior; only ever saw this when bringing up a new chip type and driver was buggy.
