We have found some networks in which nodes were constantly requesting other nodes BLA claim tables to synchronize, just to ask for that again once completed. The reason was that the crc checksum of the asked nodes were out of sync due to missing locking and multiple writes to the same crc checksum when adding/removing entries. Therefore the asked nodes constantly reported the wrong crc, which caused repeating requests. To avoid multiple functions changing a backbone gateways crc entry at the same time, lock it using a spinlock. Signed-off-by:

If the local representation of the global TT table of one originator has more VLAN entries than the respective TT update, there is some inconsistency present. By detecting and reporting this inconsistency, the global table gets updated and the excess VLAN will get removed in the process. Reported-by:

Since the function applies a threshold and also slightly worse values are accepted, ''equal or better'' does not represent the intention of the function. ''Similar or better'' represents that better. Signed-off-by:

With device tree it is no more possible to reset the PHY at board level. Furthermore, doing in the driver allow to power down the PHY when the network interface is no more used. This reset can't be done at the PHY driver level. The PHY must be able to answer the to the mii bus scan to let the kernel creating a PHY device. The patch introduces a new optional property "phy-reset-gpios" inspired from the one use for the FEC. Signed-off-by:

When sending skbs, qeth determines the number of qdio SBAL elements required. If qeth sends a fragmented skb, the SBAL element number calculation is wrong, because the fragmented data part is added twice in qeth_l3_tso_elements(). This patch makes sure fragmented data is handled in qeth_elements_for_frags() only, while qeth_l3_tso_elements() starts calculation of qdio SBAL elements just with the linear data part of the skb.

/sys/class/net/<interface>/operstate for an active qeth network interface offen shows "unknown", which translates to "state UNKNOWN in output of "ip link show". It is caused by a missing initialization of the __LINK_STATE_NOCARRIER bit in the net_device state field. This patch adds a netif_carrier_off() invocation when creating the net_device for a qeth device. Signed-off-by:

When the linear buffer of the received sk_buff is shorter than the header, use skb_linearize(). sk_buffs with short linear buffer happen on the sending side under high traffic, and some kernel configurations, when allocated buffer starts just before page boundary, and IUCV transport has to send it as two separate QDIO buffer elements, with fist element shorter than the header.

This patch removes ARPHRD_IEEE802154 from addrconf handling. In the earlier days of 802.15.4 6LoWPAN, the interface type was ARPHRD_IEEE802154 which introduced several issues, because 802.15.4 interfaces used the same type. Since commit 965e613d ("ieee802154: 6lowpan: fix ARPHRD to ARPHRD_6LOWPAN") we use ARPHRD_6LOWPAN for 6LoWPAN interfaces. This patch will remove ARPHRD_IEEE802154 which is currently deadcode, because ARPHRD_IEEE802154 doesn't reach the minimum 1280 MTU of IPv6. Also we use 6LoWPAN EUI64 specific defines instead using link-layer constanst from 802.15.4 link-layer header. Cc: David S.

AVB-DMAC Receive FIFO Warning interrupt is not enabled, so it is not necessary to disable the interrupt in ravb_close(). On the other hand, this patch disables the interrupt in ravb_dmac_init() to prevent the possibility that the interrupt is issued by the state that a boot loader left. Signed-off-by:

In commit 2a04ae8a ("hv_netvsc: remove locking in netvsc_send()"), the locking for MSD (Multi-Send Data) field was removed. This could cause a race condition between RNDIS control messages and data packets processing, because these two types of traffic are not synchronized. This patch fixes this issue by sending control messages out directly without reading MSD field. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2015-12-13 This series contains updates to fm10k only. Jacob updates the driver to use ether_addr_copy() instead of copying byte-by-byte in a for loop. Fixed up CamelCase variable names and coding style issues. Cleaned up namespace pollution of fm10k_iov_msg_data_pf(). Cleaned up, by making it consistent, the use of VLAN and VLAN ID instead of vlan or vid. Lastly, update the driver to initialize XPS so that we can take advantage of the kernel feature. Alex Duyck fixed up the driver to free the resources associated with the MSI-X vector table if the q_vector allocation failed. Then fixed the driver to check for msix_entries to be NULL and freed the IRQ if the mailbox API returned an error on trying to connect. Bruce cleans up whitespace and namespace pollution issues in the driver. Also updates the driver to use the BIT() macro instead of bit-shifting coding. ==================== Signed-off-by:
