vq log eventfd context pointer needs to be initialized, otherwise operation may fail or oops if log is enabled but log eventfd not set by userspace. When log_ctx for device is created, it is copied to the vq. This reset was missing. Reviewed-by:

vhost was dong some complex math to get offset to log at, and got it wrong by a couple of bytes, while in fact it's simple: get address where we write, subtract start of buffer, add log base. Do it this way. Reviewed-by:

Apparently bogus mc address can break IPOIB multicast processing. Therefore returning the check for addrlen back until this is resolved in bonding (I don't see any other point from where mc address with non-dev->addr_len length can came from). Signed-off-by:

This patch introduces more VPD preprocessor definitions to identify some small and large resource data type item names. The patch then continues to correct how the tg3 and bnx2 drivers search for the "read-only data" large resource data type. Signed-off-by:

The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make bcm203x_table also constant.

Move TC_PRIO_CONTROL check and queue remapping into ixgbe_select_queue(). Remapping queues after the qdisc can result in the wrong qdisc queue being stopped with netif_stop_subqueue(). Even if this is resolved and the correct queue is stopped it can result in a queue being blocked by TC_PRIO_CONTROL frames uneccesarily. Moving this into the select_queue routine maintains alignment between tx_rings and qdisc queues. Signed-off-by:

commit e8469ed959c373c2ff9e6f488aa5a14971aebe1f Author: Patrick McHardy <kaber@trash.net> Date: Tue Feb 23 20:41:30 2010 +0100 Support specifying the initial device flags when creating a device though rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING in order to surpress netlink registration notifications. To complete setup, rtnl_configure_link() must be called, which performs the device flag changes and invokes the deferred notifiers if everything went well. Two examples: # add macvlan to eth0 # $ ip link add link eth0 up allmulticast on type macvlan [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 26:f8:84:02:f9:2a brd ff:ff:ff:ff:ff:ff [ROUTE]ff00::/8 dev macvlan0 table local metric 256 mtu 1500 advmss 1440 hoplimit 0 [ROUTE]fe80::/64 dev macvlan0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 link/ether 26:f8:84:02:f9:2a [ADDR]11: macvlan0 inet6 fe80::24f8:84ff:fe02:f92a/64 scope link valid_lft forever preferred_lft forever [ROUTE]local fe80::24f8:84ff:fe02:f92a via :: dev lo table local proto none metric 0 mtu 16436 advmss 16376 hoplimit 0 [ROUTE]default via fe80::215:e9ff:fef0:10f8 dev macvlan0 proto kernel metric 1024 mtu 1500 advmss 1440 hoplimit 0 [NEIGH]fe80::215:e9ff:fef0:10f8 dev macvlan0 lladdr 00:15:e9:f0:10:f8 router STALE [ROUTE]2001:6f8:974::/64 dev macvlan0 proto kernel metric 256 expires 0sec mtu 1500 advmss 1440 hoplimit 0 [PREFIX]prefix 2001:6f8:974::/64 dev macvlan0 onlink autoconf valid 14400 preferred 131084 [ADDR]11: macvlan0 inet6 2001:6f8:974:0:24f8:84ff:fe02:f92a/64 scope global dynamic valid_lft 86399sec preferred_lft 14399sec # add VLAN to eth1, eth1 is down # $ ip link add link eth1 up type vlan id 1000 RTNETLINK answers: Network is down <no events> Signed-off-by: -

This makes the b43 driver just automatically fall back to PIO mode when DMA doesn't work. The driver already told the user to do it, so rather than have the user reload the module with a new flag, just make the driver do it automatically. We keep the message as an indication that something is wrong, but now just automatically fall back to the hopefully working PIO case.

While ath9k does not support RIFS yet, the ability to receive RIFS frames is currently enabled for most chipsets in the initvals. This is causing baseband related issues on AR9160 and AR9130 based chipsets, which can lock up under certain conditions. This patch fixes these issues by overriding the initvals, effectively disabling RIFS for all affected chipsets. Signed-off-by:

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. This patch fixes Eric Dumazet's patch to set the TX queues to the correct minimum. Signed-off-by:

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.

Work around 82599 HW issue when HWRSC is enabled on IOMMU enabled kernels. 82599 HW is updating the header information after setting the descriptor to done, resulting DMA mapping/unmapping issues on IOMMU enabled systems.
