2010-02-26can: ti hecc module : add platform specific initialization callback.Sriramakrishnan
CAN module on AM3517 requires programming of IO expander as part of init sequence - to enable CAN PHY. Added platform specific callback to handle phy control(switch on /off). Signed-off-by: Sriramakrishnan <srk@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-26Revert "ethtool: Add n-tuple string length to drvinfo and return it"David S. Miller
This reverts commit c79c5ffdce14abb4de3878c5aa8c3c6e5093c69b. As Jeff points out we can't break the user visible interface like this, we need to add this into the reserved[] thing. Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-26ipv6: Use 1280 as min MTU for ipv6 forwardingUlrich Weber
Clients will set their MTU to 1280 if they receive a ICMPV6_PKT_TOOBIG message with an MTU less than 1280. To allow encapsulating of packets over a 1280 link we should always accept packets with a size of 1280 for forwarding even if the path has a lower MTU and fragment the encapsulated packets afterwards. In case a forwarded packet is not going to be encapsulated a ICMPV6_PKT_TOOBIG msg will still be send by ip6_fragment() with the correct MTU.

The drvinfo struct should include the number of strings that get_rx_ntuple will return. It will be variable if an underlying driver implements its own get_rx_ntuple routine, so userspace needs to know how much data is coming.

2010-02-26ixgbe: Do not allocate too many netdev txqueuesJohn Fastabend
Instead of allocating 128 struct netdev_queue per device, use the minimum value between 128 and the number of possible txq's, to reduce ram usage and "tc -s -d class shod dev .." output.

2010-02-26ixgbe: do not stop tx queues in ixgbe_set_tsoJohn Fastabend
Disabling TSO can cause the dev_watchdog timer to be triggered because when TSO is disabled netif_tx_stop_all_queues is called. If the watchdog timer fires while the queues are stopped and traffic has not recently been sent on a paticular queue this is falsly identified as a hang and ndo_tx_timeout() is called. This is ocossionally seen during testing. This removes the netif_tx_stop_all_queues() it is not needed. The scheduler submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and if so it calls dev_gso_segment. Disabling TSO will cause dev_hard_start_xmit() to do the gso processing. However ixgbe does not use the features flags to determine if it needs to use tso or not instead it uses skb->gso_size so ixgbe will process these frames correctly regardless of the netdev features flag.

2010-02-26isa-skelton: Remove a wrong netif_wake_queue() callAtsushi Nemoto
The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from net_tx(). So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger tx-ring overflow.

2010-02-23net: bug fix for vlan + gro issueAjit Khaparde
Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.
