Section 1.3, pg.6 says:
| When the Switching Capability field is LSC, there is no Switching Capability specific information field present.
It should say:
| When the Switching Capability field is LSC or FSC, there is no Switching Capability specific information field present.
Location is the penultimate paragraph in Section 1.3, on mid-page 6.
In the same section, the list on top of page 5 shows the possible
Switching Capability values, their meaning and short name.
Later on, the RFC says:
The content of the Switching Capability specific information field
depends on the value of the Switching Capability field.
... and then starts to discuss the various cases.
The quoted paragraph is the last one in this discussion, and
it addresses the penultimate case in the list; the last case,
FSC, is not dealt with in any way.
Hence, the 'Switching Capability-specific information' in the
Interface Switching Capability Descriptor is underspecified.
The above correction tries to fix this deficiency to the best
knowledge of the submitter of what has been intended.
