This patch provices an EFI application to check the correct function
of the Simple Network Protocol implementation.
It sends a DHCP request and analyzes the DHCP offer.
Different error conditions including a 10s timeout are checked.
A successful execution will look like this:
=> bootefi nettest
Scanning disk ide.blk#0...
Found 1 disks
WARNING: Invalid device tree, expect boot to fail
Network test
DHCP Discover
DHCP reply received from 192.168.76.2 (52:55:c0:a8:4c:02)
as broadcast message.
OK. The test was completed successfully.

v2
move efi_st_memcmp to efi_selftest_util.c
The function can be reused for other tests.
Use constants for return values.
