NETROM is a OSI layer 3 protocol sitting on top of AX.25. It uses BCD-
encoded 10 digit telephone numbers as addresses. Without this ip will
print a ROSE addresses like
link/rose 12:34:56:78:90 brd 00:00:00:00:00
which is readable but ugly. With this applied it ROSE addresses will be
printed as
link/rose 1234567890 brd 0000000000

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.

Before this, ip would have printed the AX.25 address configured for an
AX.25 interface's default addresses as:
link/ax25 98:92:9c:aa:b0:40:02 brd a2:a6:a8:40:40:40:00
which is pretty unreadable. With this commit ip will decode AX.25
addresses like
link/ax25 LINUX-1 brd QST-0

ll_addr_n2a() correctly prints tunnel endpoints for gre, ipip, sit
and ip6tnl, but not for ip6gre. Fix this by adding ARPHRD_IP6GRE to
IPv6 tunnel endpoing address conversion.
Before:
-------
$ ip link show
...
18: ip6tnl0: <NOARP> mtu 1452 qdisc noop state DOWN mode DEFAULT group default
link/tunnel6 :: brd ::
19: ip6gre0: <NOARP> mtu 1456 qdisc noop state DOWN mode DEFAULT group default
link/gre6 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd \
00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00
After:
------
$ ip link show
...
18: ip6tnl0: <NOARP> mtu 1452 qdisc noop state DOWN mode DEFAULT group default
link/tunnel6 :: brd ::
19: ip6gre0: <NOARP> mtu 1456 qdisc noop state DOWN mode DEFAULT group default
link/gre6 :: brd ::

Apart from making the code a bit more compact and efficient, this also
prevents a potential buffer overflow if the passed buffer is really too
small: Although correctly decrementing the size parameter passed to
snprintf, it could become negative which would then wrap since snprintf
uses (unsigned) size_t for the parameter.
