Under heavy CPU load, changing, ring size/mtu/etc. could result in transmit timeout, since stop-start port might take more than 10 seconds. Calling netif_detach_device to prevent tx queue transmit timeout. netif_detach_device() is not called under ndo_stop, because netif_carrier_off will prevent the timeout, and device should not be marked as not present, or else user won't be able to start it later on.

Mac reassignments should only be done when not supported by the firmware. To accomplish that, checking firmware capability bit to know whether we should reassign macs in the driver. Signed-off-by:

The Firmware dynamically changes flow steering hash configuration from covering L2 only to "full" L2/L3/L4 mode needed. The dynamic change allows the driver to set hard coded hash configuration which is changed by the firmware from L2 to L2/L3/L4 when attaching the first L3/L4 flow steering rule and back to L2 when there are no more such rules.

Destination mac is a mandatory specification for ip/udp steering rules. When attaching multicast steering rules via ethtool the unicast mac of the interface was added to the rule specification instead of the multicast mac. The following commit sets the corresponding multicast mac for the rule multicast ip. Signed-off-by:

Supporting access to skb->pkt_type is a bit tricky if we want to have a generic code, allowing pkt_type to be moved in struct sk_buff pkt_type is a bit field, so compiler cannot really help us to find its offset. Let's use a helper for this : It will throw a one time message if pkt_type no longer starts at a byte boundary or is no longer a 3bit field. Reported-by:

Makes more sense to have randomly generated address by default than to have all zeroes. It also allows user to for example put the bond into bridge without need to have any slaves in it. Also note that this changes only behaviour of bonds with no slaves. Once the first slave device is enslaved, its address will be used (no change here). Also, fix dev_assign_type values on the way.

Instead of jumping aroung bugs that are easily fixed just don't let them in: affected drivers should be either fixed or have NETIF_F_HW_VLAN_FILTER removed from advertised features. Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features are commented out). OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't advertise NETIF_F_HW_VLAN_FILTER. Those are: +ethernet/cisco/enic/enic_main.c +ethernet/qlogic/qlcnic/qlcnic_main.c Signed-off-by:

This patch adds anti-spoofing checks in sit.c as specified in RFC3964 section 5.2 for 6to4 and RFC5969 section 12 for 6rd. I left out the checks which could easily be implemented with netfilter. Specifically this patch adds following logic (based loosely on the pseudocode in RFC3964 section 5.2): if prefix (inner_src_v6) == rd6_prefix (2002::/16 is the default) and outer_src_v4 != embedded_ipv4 (inner_src_v6) drop if prefix (inner_dst_v6) == rd6_prefix (or 2002::/16 is the default) and outer_dst_v4 != embedded_ipv4 (inner_dst_v6) drop accept To accomplish the specified security checks proposed by above RFCs, it is still necessary to employ uRPF filters with netfilter. These new checks only kick in if the employed addresses are within the 2002::/16 or another range specified by the 6rd-prefix (which defaults to 2002::/16).

* remove unused members(!): imask, ievent * move space consuming interrupt name strings (int_name_* members) to external structures, unessential for the driver's hot path * keep high priority hot path data within the first 2 cache lines This reduces struct gfar_priv_grp from 6 to 3 cache lines. (Also fixed checkpatch warnings for the old code, in the process.) Signed-off-by:

Resize and regroup structure members to eliminate memory holes and to pack the structure into 2 cache lines (from 3). tx_ring_size was resized from 4 to 2 bytes and few members were re-grouped in order to eliminate byte holes and achieve compactness. Where possible, few members were grouped according to their usage and access order (i.e. start_xmit vs. clean_tx_ring members), less important members were pushed at the end. Signed-off-by:
