2012-04-20atl1c: refine/update ASPM configurationHuang, Xiong
some platforms(BIOS or OS) may change ASPM configuration in PCI Express Link Control Register directly and dynamically regardless the device driver installation. Checking if ASPM support during the driver init phase by reading PCI Express Link Contrl Register doesn't make sense. This refine/update assume L0S/L1 is defalut enabled as hw->ctrl_flags inited. atl1c_set_aspm will set real configuration based on chip capability to hardware register. atl1c_disable_l0s_l1 and register definition of REG_PM_CTRL are refined as well.

2012-04-20stmmac: do not fail when probe and there is no csr clk definedGiuseppe CAVALLARO
On some platforms, for example where we are doing the bring-up, the csr clock is not passed from the framework and the Ethernet device driver is failing when it can work w/o any issues and using the default values. So this patch just warnings the case of the csr clock cannot be acquired but w/o failing the probe step. I have just tested it on ST STiH415 SoC (ARM).

2012-04-20stmmac: verify the dma_cfg platform fieldsGiuseppe CAVALLARO
Recently the dma parameters that can be passed from the platform have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg. In case of this new structure is not well allocated the driver can fails. This is an example how this field is managed in ST platforms static struct stmmac_dma_cfg gmac_dma_setting = { .pbl = 32, }; static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = { { .dma_cfg = &gmac_dma_setting, .has_gmac = 1, [snip] This patch so verifies that the dma_cfg passed from the platform. In case of it is NULL there is no reason that the driver has to fail and some default values can be passed. These are ok for all the Synopsys chips and could impact on performances, only.

2012-04-19bonding: start slaves with link down for ARP monitorMichal Kubeček
Initialize slave device link state as down if ARP monitor is active and net_carrier_ok() returns zero. Also shift initial value of its last_arp_tx so that it doesn't immediately cause fake detection of "up" state. When ARP monitoring is used, initializing the slave device with up link state can cause ARP monitor to detect link failure before the device is really up (with igb driver, this can take more than two seconds).

2012-04-18batman-adv: skip the window protection test when the originator has no ↵Antonio Quartulli
neighbours When we receive an OGM from from a node for the first time, the last_real_seqno field of the orig_node structure has not been initialised yet. The value of this field is used to compute the current ogm-seqno window and therefore the protection mechanism will probably drop the packet due to an out-of-window error. To avoid this situation this patch adds a check to skip the window protection mechanism if no neighbour nodes have already been added. When the first neighbour node is added, the last_real_seqno field is initialised too. Reported-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>
