2010-01-12can: Unify droping of invalid tx skbs and netdev statsOliver Hartkopp8-13/+26
To prevent the CAN drivers to operate on invalid socketbuffers the skbs are now checked and silently dropped at the xmit-function consistently. Also the netdev stats are consistently using the CAN data length code (dlc) for [rx|tx]_bytes now.

2010-01-08can: mscan-mpc5xxx: add support for the MPC512x processorWolfgang Grandegger4-95/+295
The main differences compared to the MSCAN on the MPC5200 are: - More flexibility in choosing the CAN source clock and frequency: Three different clock sources can be selected: "ip", "ref" or "sys". For the latter two, a clock divider can be defined as well. If the clock source is not specified by the device tree, we first try to find an optimal CAN source clock based on the system clock. If that is not possible, the reference clock will be used. - The behavior of bus-off recovery is configurable: To comply with the usual handling of Socket-CAN bus-off recovery, "recovery on request" is selected (instead of automatic recovery). Note that only MPC5121 Rev. 2 and later is supported. Signed-off-by: Wolfgang Grandegger <wg@denx.de> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: David S.

This patch adds a proper check of the frame lenght and data size and returns now correctly. The invalid skb packets are dropped silently as suggested by David Miller in the thread "[RFC] ndo_validate_skb: Let the netdev check a valid skb content" on the netdev mailing list.

2010-01-08ep93xx_eth.c general cleanupH Hartley Sweeten1-72/+68
General cleanup of the ep93xx_eth driver. 1) Use pr_fmt() to prefix the module name and __func__ to the error messages. 2) <linux/io.h> instead of <asm/io.h> 3) <mach/hardware.h> instead of <mach/ep93xx-regs.h> and <mach/platform.h> 4) Move the ep93xx_mdio_read (and ep93xx_mdio_write) function to eliminate the function prototype. 5) Change all the printk(<level> messages to pr_<level> and remove the __func__ argument. 6) Use platform_get_{resource/irq} to get the platform resources and add an error check. 7) Use resource_size() for request_mem_region() and ioremap(). 8) Use %pM to print the MAC address at the end of the probe. 9) Use dev->dev_addr not data->dev_addr for the MAC argument because a random address could be used if the platform does not supply one. The message at the end of the probe is left as a printk since it displays cleaner without the function name that would be displayed with pr_info().

2010-01-08bnx2: Flush the register writes which setup the MSI-X tableBenjamin Li1-0/+4
The MSI-X table size needs to be properly set before pci_enable_msix() is called. But on certain machines, the writes are delayed and the MSI-X table size is incorrectly read. By reading the BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now ensure that the MSI-X table is set correctly before MSI-X is enable on the device.

There is no difference in the PCI device ids for the two different configurations, so these drivers both claim the device ids. However, it is possible to distinguish the two configurations by the presence of Open Firmware properties for them, so we do that.
