- Added a function to check if FCS stripping is disabled by the firmware, if it is not disabled fail driver load. - By default FCS stripping is disabled by the firmware. With this assumption driver decrements the indicated packet length by 4 bytes(FCS length). - This patch ensures that FCS stripping is disabled during driver load time. Signed-off-by:

- Update driver_config->vpath_per_dev for each function in probe. - vpath_per_device specifies number of vpaths supported for each function/device. The current code was updating vpath_per_device only for physical device, however this has to be updated for each function also in case of a MF(Multi function) device. Signed-off-by:

vxge: Modify __vxge_hw_device_is_privilaged() to not assume function-0 as the privileged function: Resubmit#1 - vxge driver was assuming function-0 is always the privilaged function. Now that restriction has been removed any function can act as a privilaged function. - This patch modifies the __vxge_hw_device_is_privilaged routine to not assume function-0 as the privileged function. - Recreated the patch by incorporating review comments from Dave Miller to remove double slash in path names.

There are some switches that will do write combining when they see two sequential regions written. In order to avoid any possible write combining issues it is necessary to add a flush after writing each piece of a rar register. Signed-off-by:

This update adds additional exception handling to the phy code to handle situations where it may be called incorrectly. In addition it adds some bounds checking to the cable length checks to prevent an array overrun in the event that the hardware returned a different value than expected. Signed-off-by:

This patch adds a retry to phy reads in the event of failure. The original code broke out of the loop on failure and this is a mistake as we should be trying to do the read twice. Signed-off-by:

This patch allows us to treat the alternate mac address as though it is the physical address on the adapter. This is accomplished by letting the alt_mac_address function to only fail on an NVM error. If no errors occur and the alternate mac address is not present then RAR0 is read as the default mac address. Signed-off-by:

The mailbox timeout routines need to be updated as they were not correctly handling the case of a mailbox timeout and could cause issues with long delays when used. Signed-off-by:

Both the read and write mailbox functions need to acquire the mailbox lock. Since that is the case we might as well combine both of the procedures into one function so it is easier to maintain. Signed-off-by:

In order to support functions such as vlan tag stripping when SR-IOV is enabled any given packet must match at least one filter. However in the case of promiscous mode being enabled on the PF the traffic routed to it may not match any filters and is just sent to the PF by default. In order to make certain that this traffic is processed we can set all bits in the UTA registers to create a pseudo promiscous mode filter that accepts all packets. Signed-off-by:

The current implementation of sgmii support isn't correctly locking the interfaces for reads/writes. This change pulls the read/write functionality out of 82575.c and moves it to phy.c. In addition it replaces the implementation in 82575.c with one that uses locking around the relocated i2c interface calls. Signed-off-by:

The current approach is just using a ?: type mechanism to set the phy locking bit. This if fine for now but limits us to only 2. Switch to a nested if statement for future compatiblity with more than 2 phys. Signed-off-by:

There is a temp variable in the stats clearing path that isn't needed since the results from the stats read can be immediately discared. Since it isn't needed we might as well just drop it from the function call. Signed-off-by:

This patch exports the link-speed (in Mbps) and duplex of an interface via sysfs. This eliminates the need to use ethtool just to check the link-speed. Not requiring 'ethtool' and not relying on the SIOCETHTOOL ioctl should be helpful in an embedded environment where space is at a premium as well. NOTE: This patch also intentionally allows non-root users to check the link speed and duplex -- something not possible with ethtool. Here's some sample output: # cat /sys/class/net/eth0/speed 100 # cat /sys/class/net/eth0/duplex half # ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: Not reported Advertised auto-negotiation: No Speed: 100Mb/s Duplex: Half Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: g Wake-on: g Current message level: 0x000000ff (255) Link detected: yes Signed-off-by: -

Instead of having to modify every non-mac80211 for device type assignment, do this inside the netdev notifier callback of cfg80211. So all drivers that integrate with cfg80211 will export a proper device type. Signed-off-by:

For various purposes including a wireless extensions bugfix, we need to hook into the netdev creation before before netdev_register_kobject(). This will also ease doing the dev type assignment that Marcel was working on for cfg80211 drivers w/o touching them all. Signed-off-by:

We currently dirty a cache line to update tunnel device stats (tx_packets/tx_bytes). We better use the txq->tx_bytes/tx_packets counters that already are present in cpu cache, in the cache line shared with txq->_xmit_lock This patch extends IPTUNNEL_XMIT() macro to use txq pointer provided by the caller. Also &tunnel->dev->stats can be replaced by &dev->stats Signed-off-by:

Add Ancilliary data to better represent loss information I've had a few requests recently to provide more detail regarding frame loss during an AF_PACKET packet capture session. Specifically the requestors want to see where in a packet sequence frames were lost, i.e. they want to see that 40 frames were lost between frames 302 and 303 in a packet capture file. In order to do this we need: 1) The kernel to export this data to user space 2) The applications to make use of it This patch addresses item (1). It does this by doing the following: A) Anytime we drop a frame for which we would increment po->stats.tp_drops, we also no increment a stats called po->stats.tp_gap. B) Every time we successfully enqueue a frame to sk_receive_queue, we record the value of po->stats.tp_gap in skb->mark. skb->cb would nominally be the place to record this, but since all the space there is used up, we're overloading skb->mark. Its safe to do since any enqueued packet is guaranteed to be unshared at this point, and skb->mark isn't used for anything else in the rx path to the application. After we record tp_gap in the skb, we zero po->stats.tp_gap. This allows us to keep a counter of the number of frames lost between any two enqueued packets C) When the application goes to dequeue a frame from the packet socket, we look at skb->mark for that frame. If it is non-zero, we add a cmsg chunk to the msghdr of level SOL_PACKET and type PACKET_GAPDATA. Its a 32 bit integer that represents the number of frames lost between this packet and the last previous frame received. Note there is a chance that if there is frame loss after a receive, and then the socket is closed, some gap data might be lost. This is covered by the use of the PACKET_AUXDATA socket option, which gives total loss data. With a bit of math, the final gap can be determined that way. I've tested this patch myself, and it works well. Signed-off-by:

We can make icmp messages tx completion callback a litle bit faster. Setting SOCK_USE_WRITE_QUEUE sk flag tells sock_wfree() to not call sk_write_space() on a socket we know no thread is posssibly waiting for write space. (on per cpu kernel internal icmp sockets only) This avoids the sock_def_write_space() call and read_lock(&sk->sk_callback_lock)/read_unlock(&sk->sk_callback_lock) calls as well. We avoid three atomic ops. Signed-off-by:

I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when 'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about whether people perhaps meant -rc1 or -rc2.
