The member "clock" of struct "sja1000_platform_data" is documented as "CAN bus oscillator frequency in Hz" but it's actually used as the CAN clock frequency, which is half of it. To avoid further confusion, this patch fixes it by renaming the member to "osc_freq". That way, also non mainline users will notice the change. The platform code for the relevant boards is updated accordingly. Furthermore, pre-defined values are now used for the members "ocr" and "cdr". Signed-off-by:

skb rxhash should be cleared when a skb is handled by a tunnel before being delivered again, so that correct packet steering can take place. There are other cleanups and accounting that we can factorize in a new helper, skb_tunnel_rx() Signed-off-by:

Commit 33ad798c (tcp: options clean up) introduced a problem if MD5+SACK+timestamps were used in initial SYN message. Some stacks (old linux for example) try to negotiate MD5+SACK+TSTAMP sessions, but since 40 bytes of tcp options space are not enough to store all the bits needed, we chose to disable timestamps in this case. We send a SYN-ACK _without_ timestamp option, but socket has timestamps enabled and all further outgoing messages contain a TS block, all with the initial timestamp of the remote peer. Fix is to really disable timestamps option for the whole session. Reported-by:

The duplicate address check code got broken in the conversion to hlist (2.6.35). The earlier patch did not fix the case where two addresses match same hash value. Use two exit paths, rather than depending on state of loop variables (from macro). Based on earlier fix by Shan Wei. Signed-off-by:

dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and net_device_ops respectively). This causes a spinlock recursion BUG. Fix this by renaming these functions to *_unlocked for the atomic context, and make the original functions locking wrappers for use in the non-atomic context.

When attaching filters to a class pointing to a class higher up in the hierarchy, classification may enter an endless loop. Currently this is prevented for filters that are already resolved, but not for filters resolved at runtime. Only allow filters to point downwards in the hierarchy, similar to what CBQ does.

The current link checking logic only works for one port, which is not correct for swiches were multiple ports can have different link status. As a result we would only check for link status on port 1 of the switch. Move the calls to mii_check_media in r6040_timer which will be polling a single PHY chip correctly and assume link is up for switches. Signed-off-by:

These callbacks were needed because dev_pm_ops support for OF platform devices was in the powerpc tree, and the patch that added dev_pm_ops for gianfar driver was in the netdev tree. Now that netdev and powerpc trees have merged into Linus' tree, we can remove the legacy hooks. Signed-off-by:

Several netem users use TBF for rate control. But every time the parameters of TBF are changed it destroys the child qdisc, requiring reconfigation. Better to just keep child qdisc and just notify it of changed limit. Signed-off-by:

Based on original patch from Stanislaw Gruszka <sgruszka@redhat.com>. Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start(). Again, the phy_lock prevents race conditions with the serdes timers. Signed-off-by:

IP checksum is based on 16-bit one's complement algorithm, so to deduce a value from checksum is equal to add its complement. Unfortunately, the Blackfin on-chip MAC checksum logic only works when the IP packet has a header length of 20 bytes. This is true for most IPv4 packets, but not for IPv6 packets or IPv4 packets which use header options. So only use the hardware checksum when appropriate. Signed-off-by:

The skb buffer isn't actually used until we finish transferring and pass it up to higher layers, so only invalidate the range once before we start receiving actual data. This also avoids the problem with data invalidating on Blackfin systems -- there is no invalidate-only, just invalidate+flush. So when running in writeback mode, there is the small (but not uncommon) possibility of the flush overwriting valid DMA-ed data from the cache. Signed-off-by:
