On the platforms that mv643xx_eth is used on, the manual skb->data alignment logic in mv643xx_eth can be simplified, as the only case we need to handle is where NET_SKB_PAD is not a multiple of the cache line size. If this is the case, the extra padding we need can be computed at compile time, while if NET_SKB_PAD _is_ a multiple of the cache line size, the code can be optimised out entirely.

v5 -> v6 (current): -removed so far unused static functions -corrected dev_addr_del_multiple to call del instead of add v4 -> v5: -added device address type (suggested by davem) -removed refcounting (better to have simplier code then safe potentially few bytes) v3 -> v4: -changed kzalloc to kmalloc in __hw_addr_add_ii() -ASSERT_RTNL() avoided in dev_addr_flush() and dev_addr_init() v2 -> v3: -removed unnecessary rcu read locking -moved dev_addr_flush() calling to ensure no null dereference of dev_addr v1 -> v2: -added forgotten ASSERT_RTNL to dev_addr_init and dev_addr_flush -removed unnecessary rcu_read locking in dev_addr_init -use compare_ether_addr_64bits instead of compare_ether_addr -use L1_CACHE_BYTES as size for allocating struct netdev_hw_addr -use call_rcu instead of rcu_synchronize -moved is_etherdev_addr into __KERNEL__ ifdef This patch introduces a new list in struct net_device and brings a set of functions to handle the work with device address list. The list is a replacement for the original dev_addr field and because in some situations there is need to carry several device addresses with the net device. To be backward compatible, dev_addr is made to point to the first member of the list so original drivers sees no difference. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: David S.

This should be very safe compared with full enabled, so I see no reason why it shouldn't be done right away. As ECN can only be negotiated if the SYN sending party is also supporting it, somebody in the loop probably knows what he/she is doing. If SYN does not ask for ECN, the server side SYN-ACK is identical to what it is without ECN. Thus it's quite safe. The chosen value is safe w.r.t to existing configs which choose to currently set manually either 0 or 1 but silently upgrades those who have not explicitly requested ECN off. Whether to just enable both sides comes up time to time but unless that gets done now we can at least make the servers aware of ECN already. As there are some known problems to occur if ECN is enabled, it's currently questionable whether there's any real gain from enabling clients as servers mostly won't support it anyway (so we'd hit just the negative sides). After enabling the servers and getting that deployed, the client end enable really has some potential gain too. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

Based almost entirely upon a patch by Eric Dumazet. The common case is to have num-tx-queues <= num_rx_queues and even if num_tx_queues is larger it will not be significantly larger. Therefore, a subtraction loop is always going to be faster than modulus. Signed-off-by: David S. Miller <davem@davemloft.net>

The kernel should only be using the high 16 bits of a kernel generated priority. Filter priorities in all other cases only use the upper 16 bits of the u32 'prio' field of 'struct tcf_proto', but when the kernel generates the priority of a filter is saves all 32 bits which can result in incorrect lookup failures when a filter needs to be deleted or modified.

LAN9512 and LAN9514 are USB hubs with an integrated 10/100 ethernet controller. Logically this looks like an ethernet controller (similar to LAN9500) permanently attached to one of the hub's downstream ports. This patch adds the usb device id of the new ethernet controller to the smsc95xx driver. This id is the same in both new devices.

When netconsole is loaded and a network interface fades away (e.g. on rmmod $interface_driver_module) the rmmod remains stuck and some locks are taken that prevent any additional module loading/unloading as well as interface up/down changes. In addition kernel logs (and console) get flooded at 10s interval with [ 122.464065] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 [ 132.704059] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 This patch lets netconsole take NETDEV_UNREGISTER event into account and release the affected interface if it was in use.
