The iwmc3200 driver selects other code in Kconfig that depends on EXPERIMENTAL. Kconfig warns about this when CONFIG_EXPERIMENTAL is not already set, so logically, these options should also be marked experimental or promoted to stable.

The caif_shmcore requires io.h in order to use ioremap, so include that explicitly to compile in all configurations. Also add a note about the use of ioremap(), which is not a proper way to map a DMA buffer into kernel space. It's not completely clear what the intention is for using ioremap, but it is clear that the result of ioremap must not simply be accessed using kernel pointers but should use readl/writel or memcopy_{to,from}io. Assigning the result of ioremap to a regular pointer that can also be set to something else is not ok.

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.

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).

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.

Also shift initial value of its last_arp_tx so that it doesn't immediately cause fake detection of "up" state.
