iSCSI: Extension Keys in Discovery Mode

[Russell Lewis <russelll@us.ibm.com>]

I'm looking at spec 0.19, section 12.22, and it says "Vendor specific keys
MUST ONLY be used in normal sessions."

1) Am I correct that it means that it is also illegal to pass vendor
specific keys during LOGIN if the session is going to be Discovery?
2) Does anybody know why this requirement is in the spec?

Thanks,
Russ Lewis
