Sofar far pktgen have had a restriction to only use one device per kernel thread. With the new multiqueue architecture this is no longer adequate. The patch below is an effort to remove this by in pktgen configuration adding a tag to the device name a la eth0@0 etc. The tag is used for usual device config just as before. Also a new flag is introduced to mirror queue_map with sending threads smp_processor_id() QUEUE_MAP_CPU. An example: We use 4 CPU's to send to one 10g interface (eth0) and we use the new tagging to send a mix of packet sizes, 64, 576 and 1500 bytes. Also we use TX queues according to smp_processor_id() PGDEV=/proc/net/pktgen/kpktgend_0 pgset "add_device eth0@0" PGDEV=/proc/net/pktgen/kpktgend_1 pgset "add_device eth0@1" PGDEV=/proc/net/pktgen/kpktgend_2 pgset "add_device eth0@2" PGDEV=/proc/net/pktgen/kpktgend_3 pgset "add_device eth0@3" ....

Allow a packet_type that specifies the exact device to receive even on an inactive bonding slave devices. This is important for some L2 protocols such as LLDP and FCoE. This can eventually be used for the bonding special cases as well. Signed-off-by:

It is wrong to destroy a bonding master from a context that uses the sysfs of that bond. When last IPoIB slave is unenslaved from by writing to a sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves) the driver tries to destroy the bond. This is wrong and can lead to a lockup or a crash. This fix lets the bonding master stay and relies on the user to destroy the bonding master if necessary (i.e. before module ib_ipoib is unloaded) This patch affects only bonds of IPoIB slaves. Ethernet slaves stay unaffected. Signed-off-by:

Refactor mii monitor. As with the previous ARP monitor refactor, the motivation for this is to handle locking rationally (in this case, removing conditional locking) and generally clean up the code. This patch breaks up the monolithic mii monitor into two phases: an inspection phase, followed by an optional commit phase. The commit phase is the only portion that requires RTNL or makes changes to state, and is only called when inspection finds something to change. Signed-off-by:

If the following packet flow happen, kernel will panic. MathineA MathineB SYN ----------------------> SYN+ACK <---------------------- ACK(bad seq) ----------------------> When a bad seq ACK is received, tcp_v4_md5_do_lookup(skb->sk, ip_hdr(skb)->daddr)) is finally called by tcp_v4_reqsk_send_ack(), but the first parameter(skb->sk) is NULL at that moment, so kernel panic happens. This patch fixes this bug.

Some hardware set promisc when they are requested to set IFF_ALLMULTI flag. It's ok, but if drivers set IFF_PROMISC flag when they set promisc, it will broken upper layer handle for promisc and allmulti. In addition, drivers can use their own hardware programming to make it. So do not allow drivers to set IFF_* flags. This is a general driver fix, so I didn't split it to pieces and send to specific driver maintainers. Signed-off-by:

Fix possible bug where end of receive buffer could be overwritten. The allocation needs to allow for the reserved space. This would only happen if device received packet greater than Ethernet standard MTU. Change this driver to use netdev_alloc_skb rather than setting skb->dev directly. For the initial allocation it doesn't need to be GFP_ATOMIC. Signed-off-by:

Introduce the speed_hi field to ethtool_cmd, using the reserved space, to expand the speed field to 2^32 Megabits/second. Making this field expansion now gives us plenty of time to fix up the user-space pieces that use SIOCETHTOOL before hardware faster than 64 Gb/s is available. Signed-off-by:
