Some real DHCP servers dont set the siaddr field in the DHCPOffer to
their IPv4 (and instead leave it blank - 0.0.0.0), which results in
the server assuming the DHCPRequest is not directed at him when it
has the ServerIdentifier option attached that specifies 0.0.0.0 as
the targeted server. So instead we just omit the option and let the
DHCP servers decipher the target themselves based on the requested IP.
The current parsing code assumed the ascii lowercase letters came after
the ascii numbers, which is not the case, and as such corrupted any mac
address that included hex letters (a-f). We likely did not notice this
as QEMU's emulated MAC is made up of only hex digits.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
