This removes the following checkpatch warning:
- WARNING: line over 80 characters
There are three such warnings left.
The first is hard to fix with cosmetic-only changes without compromising code
readability, so I'm leaving it as it is for now:
WARNING: line over 80 characters
#1537: FILE: net.c:1537:
+ [4 tabs] memcpy(((Ethernet_t *)NetArpWaitTxPacket)->et_dest, ...
The other two cannot be fixed without splitting string literals, so it is
preferred to keep them longer than 80 characters.

Changes since v1:
- do not split string literals (even though this means leaving the line
longer than 80 characters).
