RE: FCIP - Proposed changes in support of common FC encapsulation

[Sudhir Srinivasan <SudhirS@trebia.com>]

Ralph,

My preference is to reference Section 8.1 - here's
a suggestion:

"The FCIP receiving device MUST reverse the FC frame 
encapsulation process, verify the correctness of the header 
and deliver the FC frames to the correct FC ports connected 
to the FCIP device. When header errors are encountered in
FCIP data frames, the FCIP device MUST take corrective 
action in accordance with Section 8.1."

Sudhir,

Do you think it would be better to delete the "discarding frames
with header errors" part entirely or to reword it to be more of
a reference to 8.1?

Thanks.

Ralph...
