Re: [PATCH V2] net: mhi : Add support to enable ethernet interface

[Vivek Pernamitta]

Currently MHI NET driver does not support Ethernet interface,

we are adding Ethernet interface support to MHI NET driver, so new 
client can be configured to be Ethernet type over MHI by setting 
"mhi_device_info.ethernet_if = true"

currently we are not changing mhi_swip0/mhi_hwip0 to Ethernet. we are 
adding an provision to configure mhi client as  Ethernet type.

yes ,it is false as by default mhi_swip/mhi_hwip interface will be 
normal net device.
