We don't want executable APKBUILDs, deviceinfo files, etc in pmaports. Remove the executable bit from those files. [ci:skip-build] [ci:skip-vercheck]

Subject: [PATCH 5/6] usb_gadget: set random rndis host MAC address to prevent
|
|
zero address
|
|
|
|
This fixes zero host MAC:
|
|
|
|
rndis0: MAC f6:45:91:9b:4e:43
|
|
rndis0: HOST MAC 00:00:00:00:00:00
|
|
|
|
and allows devive to automatically obtain IP addrest on PC host side
|
|
zero MAC address prevented interface from autoconfiguring
|
