0x8035 is RARP. RARP is used by diskless clients to obtain their IP
address from a server using their ethernet address as a key. This is
the opposite of ARP, hence the name RARP.
Note that the kernel only replies to RARP requests if it was compiled
with CONFIG_INET_RARP enabled. It only sends RARP requests if it was
compiled with CONFIG_RNFS_RARP enabled.

0x0806 is ARP, which is necessary for using IP over ethernet.
