Introduce the DPAA2 Ethernet driver, which manages Datapath Network Interface (DPNI) objects discovered on the MC bus. In addition to DPNIs, the Ethernet driver uses several other MC objects to build a network interface abstraction: buffer pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs). A more detailed description of the driver can be found in the associated README file. Signed-off-by:

This patch adds the command building/parsing wrapper functions for the DPCON object. The binary interface version is v3.2. A DPCON (DataPath Concentrator) is an aggregator object that allows ingress frames from multiple hardware queues to be seen as coming from a single source, from the CPU point of view. Signed-off-by:

I ran into this warning during randconfig testing: drivers/staging/rtl8723bs/os_dep/rtw_proc.c: In function 'rtw_adapter_proc_deinit': drivers/staging/rtl8723bs/os_dep/rtw_proc.c:738:25: error: unused variable 'drv_proc' [-Werror=unused-variable] drivers/staging/rtl8723bs/os_dep/rtw_proc.c: In function 'rtw_adapter_proc_replace': drivers/staging/rtl8723bs/os_dep/rtw_proc.c:762:25: error: unused variable 'drv_proc' [-Werror=unused-variable] The problem is that the code procfs code gets built even when CONFIG_PROC_FS is disabled, but some functions are turned into empty stubs then. This is easily addressed by adding an #ifdef around the definition of the CONFIG_PROC_DEBUG macro. However, I could not bear looking at the macro name that clashes with the Kconfig name space, so I also renamed it to simply PROC_DEBUG, along with the other rtl8723bs specific CONFIG_DEBUG_* macros that I renamed the same way. This is consistent with how we handle the same checks in the non-staging rtlwifi driver. As the code path for !CONFIG_PROC_DEBUG had not been tested properly, it turned out to be incorrect and requires adding 'static inline' annotations for the stub handlers, and moving some variables around.

Removed the usb_device_reset(), replace with call to usb_reset_device() directly. Plus it removes the confusing function name and addressed the checkpatch warning. This change also swaps string in the dev_warn() call with __func__ argument to "vt6656_probe" instead of literal string "usb_reset_device".
