Hi there!
My machine is an Acer Aspire R3-131T, the firmware installed is the

Greetings,
Having a slight issue with getting reboot to work on the board I'm tinkering
with; according to the documentation writing any value to 0x12050004 should
reset the system, as such I have the following snippet in my dts to make it
work:

gso_type is being used in binary AND operations together with SKB_GSO_UDP.
The issue is that variable gso_type is of type unsigned short and
SKB_GSO_UDP expands to more than 16 bits:
SKB_GSO_UDP = 1 << 16
this makes any binary AND operation between gso_type and SKB_GSO_UDP to
be always zero,
