Guy Harris 1cca166630 Make the "isis_hello.source_id" an FT_BYTES field rather than an
FT_ETHER field; the ISIS spec doesn't say it's necessarily a 6-byte
Ethernet address (and, if it's FT_BYTES, you can test it in a filter
much the same way you test an Ethernet address).

Make "isis_hello.lan_id" an FT_BYTES field rather than an FT_STRING
field - it's an array of bytes, not a character string.

Don't require that "system ID" fields be 6 octets; use the size value
from the ISIS PDU header.  (This means that PDUs containing "system ID"
fields can't be described as C structures; dissect them by stepping the
offset instead.)
