This patch fixes the driver so that multicast PTP event messages can be recognized by the hardware time stamping unit. The station address register must be set according to the desired transport type. [ RC - Rebased Takahiro's changes and wrote a commit message explaining the changes. ] Signed-off-by:

All of the users have been converted to use registera_net_sysctl so we no longer need register_net_sysctl. Signed-off-by:

This results in code with less boiler plate that is a bit easier to read. Additionally stops us from using compatibility code in the sysctl core, hastening the day when the compatibility code can be removed. Signed-off-by:

There isn't much advantage here except that strings paths are a bit easier to read, and converting everything to them allows me to kill off ctl_path. Signed-off-by:

Using an ascii path to register_net_sysctl as opposed to the slightly awkward ctl_path allows for much simpler code. We no longer need to malloc dev_name to keep it alive the length of our sysctl register instead we can use a small temporary buffer on the stack. Signed-off-by:

Don't register/unregister every ax25 table in a batch. Instead register and unregister per device ax25 sysctls as ax25 devices come and go. This moves ax25 to be a completely modern sysctl user. Registering the sysctls in just the initial network namespace, removing the use of .child entries that are no longer natively supported by the sysctl core and taking advantage of the fact that there are no longer any ordering constraints between registering and unregistering different sysctl tables.

sysctl no longer requires explicit creation of directories. The neigh directory is always populated with at least a default entry so this won't cause any user visible changes. Delete the ipv4_path and the ipv4_skeleton these are no longer needed. Directly register the ipv4_route_table. And since I am an idiot remove the header definitions that I should have removed in the previous patch. Signed-off-by:

This makes it clearer which sysctls are relative to your current network namespace. This makes it a little less error prone by not exposing sysctls for the initial network namespace in other namespaces. This is the same way we handle all of our other network interfaces to userspace and I can't honestly remember why we didn't do this for sysctls right from the start. Signed-off-by:

register_sysctl_rotable never caught on as an interesting way to register sysctls. My take on the situation is that what we want are sysctls that we can only see in the initial network namespace. What we have implemented with register_sysctl_rotable are sysctls that we can see in all of the network namespaces and can only change in the initial network namespace. That is a very silly way to go. Just register the network sysctls in the initial network namespace and we don't have any weird special cases to deal with. The sysctls affected are: /proc/sys/net/ipv4/ipfrag_secret_interval /proc/sys/net/ipv4/ipfrag_max_dist /proc/sys/net/ipv6/ip6frag_secret_interval /proc/sys/net/ipv6/mld_max_msf I really don't expect anyone will miss them if they can't read them in a child user namespace.

If the netfilter code is modified to use register_net_sysctl_table the kernel fails to boot because the per net sysctl infrasturce is not setup soon enough. So to avoid races call net_sysctl_init from sock_init(). Signed-off-by:

Implementation limitations of the sysctl core won't let /proc/sys/net reside in a network namespace. /proc/sys/net at least must be registered as a normal sysctl. So register /proc/sys/net early as an empty directory to guarantee we don't violate this constraint and hit bugs in the sysctl implementation. Signed-off-by:

Right now all of the networking sysctl registrations are running in a compatibiity mode. The natvie sysctl registration api takes a cstring for a path and a simple ctl_table. Implement register_net_sysctl so that we can register network sysctls without needing to use compatiblity code in the sysctl core. Switching from a ctl_path to a cstring results in less boiler plate and denser code that is a little easier to read. I would simply have changed the arguments to register_net_sysctl_table instead of keeping two functions in parallel but gcc will allow a ctl_path pointer to be passed to a char * pointer with only issuing a warning resulting in completely incorrect code can be built. Since I have to change the function name I am taking advantage of the situation to let both register_net_sysctl and register_net_sysctl_table live for a short time in parallel which makes clean conversion patches a bit easier to read and write.

bit PCIE_PHYMISC_FORCE_RCV_DET is only for l1c&l2c to fix WoL issue, other chips set bit5 of REG_MASTER_CTRL --- this way could save more power than the former, and the bit should be kept all time. l2cb 1.x has special setting for L0S/L1 l2cb 1.x & l1d 1.x should clear Vendor Message on some platforms, otherwise it will cause the root complex hang.

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.

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). Signed-off-by:

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.
