Subject: [PATCH 4/6] NETROM: Print decoded addresses rather than hex numbers.

NETROM is an OSI layer 3 protocol sitting on top of AX.25.  It also uses
AX.25 addresses.  Without this commit ip will print NETROM address like

  link/generic 98:92:9c:aa:b0:40:02 brd 00:00:00:00:00:00:00

while with this commit the decoded result

  link/generic LINUX-1 brd *

is much more eye friendly.
