2013-03-07Merge branch 'tg3'David S. Miller
Nithin Nayak says: ==================== For the 57766 devices with no NVRAM, there is not enough space for the complete boot code with EEE support. On these devices, the tg3 driver has to download a service patch firmware to the scratchpad for the boot code to execute. This patchset adds support to do the above. A major portion of this patchset is refactoring the existing firmware download section to allow a cleaner merge of the 57766 download. The 57766 firmware differs from previous firmware in that it's not written to a contiguous area in memory. It consists of multiple fragments to be written to different locations. The patchset makes an attempt to make the new firmware format to be an extension of the existing format. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-03-07tg3: Cleanup firmware parsing codeNithin Sujir
The current firmware header parsing is complicated due to interpreting it as a u32 array and accessing header members via array offsets. Add tg3_firmware_hdr structure to access the firmware fields instead of hardcoding offsets. The same header format will be used for individual firmware fragments in the 57766. The fw_hdr and tg3 structures have all the information required for loading the fw. Remove the redundant fw_info structure and pass fw_hdr instead.

Vlad Yasevich says: ==================== This is a short series that now allows mac filter programming on any card that support IFF_UNICAST_FLT by using the existing FDB interface. Some existing drivers that had FDB functionality usually supported it only in SR-IOV mode. Since that's not always enabled, and we want to take advantage of IFF_UNICAST_FLT support, these drivers have been converted to call the default handler when not in SRIOV mode. ==================== Signed-off-by: David S.

Untill the driver is fully fixed, this allows the use of the FDB interface with qlogic driver, but simply puts the driver into promisc mode since the driver currently does not support IFF_UNICAST_FLT.

2013-03-07net: generic fdb support for drivers without ndo_fdb_<op>Vlad Yasevich
If the driver does not support the ndo_op use the generic handler for it. This should work in the majority of cases. Eventually the fdb_dflt_add call gets translated into a __dev_set_rx_mode() call which should handle hardware support for filtering via the IFF_UNICAST_FLT flag. Namely IFF_UNICAST_FLT indicates if the hardware can do unicast address filtering. If no support is available the device is put into promisc mode.

virtio_rng feeds the randomness buffer handed by the core directly into the scatterlist, since commit bb347d98079a547e80bd4722dee1de61e4dca0e8. However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address (at least on most archs). We could fix this in virtio_rng, but it's actually far easier to just do it in the core as virtio_rng would have to allocate a buffer every time (it doesn't know how much the core will want to read).
