2010-09-15misdn: kill big kernel lockArnd Bergmann
The use of the big kernel lock in misdn is completely bogus, so let's just remove it. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Karsten Keil <isdn@linux-pingi.de> Cc: netdev@vger.kernel.org Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-15i4l: kill big kernel lockArnd Bergmann
The isdn4linux driver uses the big kernel lock only to serialize access to a few fields in its own modem_info structure. The easiest replacement is a driver-wide mutex. More fine-grained locking would be more appropriate here, but likely harder to implement.

2010-09-15ethtool: Remove unimplemented flow specification typesBen Hutchings
struct ethtool_rawip4_spec and struct ethtool_ether_spec are neither commented nor used by any driver, so remove them. Adjust padding in the user-visible unions that included these structures. Fix references to struct ethtool_rawip4_spec in ethtool_get_rx_ntuple(), which should use struct ethtool_usrip4_spec. struct ethtool_usrip4_spec cannot hold IPv6 host addresses and there is no separate structure that can, so remove ETH_RX_NFC_IP6 and the reference to it in niu.

2010-09-15tg3: phy tmp variable roundupMatt Carlson

2010-09-15tg3: Move producer ring struct to tg3_napiMatt Carlson
Now that each NAPI instance has its own producer ring, it no longer makes sense to keep the producer ring structure external. This patch migrates the producer ring struct to tg3_napi and pivots the code to the new implementation.

2010-09-15tg3: Clarify semantics of TG3_IRQ_MAX_VECSMatt Carlson
TG3_IRQ_MAX_VECS should be seen as the maximum number of vectors that any device could be expected to use. tp->irq_max represents the maximum number of vectors the current device can use.

2010-09-15tg3: Don't send APE events for NCSI firmwareMatt Carlson
NCSI firmware does not accept APE events. It relies on a "driver state" location in shared memory to tell it what the driver's current state is.

2010-09-15tg3: Fix read DMA FIFO overruns on recent devicesMatt Carlson
Earlier versions of tg3 devices had a problem where the read DMA FIFO could be overrun in certain edge conditions. The fix was to limit the number of rx BDs the hardware would fetch at a time. For later devices (5761, 5784 and later ASIC revs), there is a hardware fix that must be enabled to fix the same problem. This patch adds that hardware fix. There is a gap in the ASIC revision lineage where neither fix is applied. This is intentional as these ASIC revisions are not afflicted by the bug.

2010-09-10sfc: Allocate DMA and event rings using GFP_KERNELBen Hutchings
Currently we allocate DMA descriptor rings and event rings using pci_alloc_consistent() which selects non-blocking behaviour from the page allocator (GFP_ATOMIC). This is unnecessary, and since we currently allocate a single contiguous block for each ring (up to 32 pages!) these allocations are likely to fail if there is any significant memory pressure. Use dma_alloc_coherent() and GFP_KERNEL instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-10sfc: Accumulate RX_NODESC_DROP count in rx_dropped, not rx_over_errorsBen Hutchings
rx_over_errors appears to be intended as a count of packets that overflow a packet buffer in the NIC. Given that we implement a cut-through receive path, this should always be 0. rx_dropped appears to be the correct counter for packets dropped due to lack of host buffers.

2010-09-10sfc: Use MCDI RX_BAD_FCS_PKTS count as MAC rx_bad countBen Hutchings

The 'wwan' devtype is meant for devices that require preconfiguration and *every* time setup before the ethernet interface can be used, like cellular modems which require a series of setup commands on serial ports or other mechanisms before the ethernet interface will handle packets. As ipheth only requires one-per-hotplug pairing setup with no preconfiguration (like APN, phone #, etc) and the network interface is usable at any time after that initial setup, remove the incorrect devtype wwan.
