* team: remove synchronize_rcu() called during queue override changeJiri Pirko2013-06-121-16/+47
| | | | | | | | | | | | | This patch removes synchronize_rcu() from function __team_queue_override_port_del(). That can be done because it is ok to do list_del_rcu() and list_add_tail_rcu() on the same list_head member without calling synchronize_rcu() in between. A bit of refactoring needed to be done because INIT_LIST_HEAD needed to be removed (to not kill the forward pointer) as well.

| | | | | | | | | | | | | | | | | | | | | | | | | Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch which needs to be driven slightly differently from the traditional external switches. This patch introduces changes in arch/mips/bcm63xx in order to: - register a bcm63xx_enetsw driver instead of bcm63xx_enet driver - update DMA channels configuration & state RAM base addresses - add a new platform data configuration knob to define the number of ports per switch/device and force link on some ports - define the required switch registers On the driver side, the following changes are required: - the switch ports need to be polled to ensure the link is up and running and RX/TX can properly work - basic switch configuration needs to be performed for the switch to forward packets to the CPU - update the MIB counters since the integrated Signed-off-by: Maxime Bizon <mbizon@freebox.fr> Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | The current bcm63xx_enet driver always uses bcmenet_shared_base whenever it needs to access DMA channel configuration space or access the DMA channel state RAM. Split these register in 3 parts to be more accurate: - global DMA configuration - per DMA channel configuration space - per DMA channel state RAM space This is preliminary to support new chips where the global DMA configuration remains the same, but there is a varying number of DMA channels located at a different memory offset.

This is used to be compatible at API layer of tuntap to simplify the userspace to manage the queues.

* macvtap: eliminate linear searchJason Wang2013-06-081-44/+20Star
| | | | | | | | | | | | | | | | | | | Linear search were used in both get_slot() and macvtap_get_queue(), this is because: - macvtap didn't reshuffle the array of taps when create or destroy a queue, so when adding a new queue, macvtap must do linear search to find a location for the new queue. This will also complicate the TUNSETQUEUE implementation for multiqueue API. - the queue itself didn't track the queue index, so the we must do a linear search in the array to find the location of a existed queue. The solution is straightforward: reshuffle the array and introduce a queue_index to macvtap_queue. Signed-off-by: Jason Wang <jasowang@redhat.com> Acked-by: Michael S.

This may lead a race if vlan->numvtaps were changed in the same time and which can lead unexpected result (e.g. very huge value).

Start by creating the initial table with driver's name as the only entry without the driver data. Check the driver data in the probe() method and if it's not NULL override 'mdp->cd' from it.

* bonding: disallow change of MAC if fail_over_mac enabledJay Vosburgh2013-06-081-4/+3Star
| | | | | | | | | | | | | | | | Currently, if fail_over_mac is set to active, then attempts to change the MAC of the bond itself silently fail. However, if fail_over_mac is set to follow, changes are permitted. Permitting the bond's MAC to change with fail_over_mac=follow will disrupt the follow functionality, which normally controls the assignment of MAC address to the bond and its slaves, and can cause multiple ports to be assigned the same MAC address. which will interfere with the functioning of the device (where the device here is a virtualization-aware card for s390, qeth).

Calls to dev_uc_sync and dev_uc_sync_multiple are also added, so that unicast addresses added to a bond will be properly synced with its slaves. Various functions are renamed to better reflect the new situation, and relevant comments are updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 091f0ea30074bc43f9250961b3247af713024bc6 "tg3: Add New 5719 Read DMA workaround" added a workaround for TX DMA stall on the 5719. This workaround needs to be applied to the 5720 as well.

| * net: ethernet: xilinx_emaclite: set protocol selector bits when writing ANARJens Renner \(EFE\)2013-06-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sets the protocol selector bits (4:0) of the PHY's MII_ADVERTISE register (ANAR) when writing ADVERTISE_ALL. The protocol selector bits are indicating IEEE 803.3u support and are fixed / read-only on some PHYs. Not setting them correctly on others (like TI DP83630) makes the PHY fall back to 10M HDX mode which should be avoided. Tested for TI DP83630 PHY on Microblaze platform.

| * bnx2x: Fix bridged GSO for 57710/57711 chipsYuval Mintz2013-06-051-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was recently found out that GSO on 57710/57711 was broken, due to packets being sent without a valid IP checksum. Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this issue, but failed to set the correct IP checksum when receiving GSO packets via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed to calculate IP checksum were erroneously set in the incorrect buffer descriptor. This patch re-enables GSO in said scenario for 57710/57711 chips.

The last two patches by Olivier Sobrie (for esd_usb2) and me (for peak_usb) change the memory handling for the USB messages from stack to kmalloc(), as memory used for DMA should not be allocated on stack. ==================== Signed-off-by: David S.
