Subject: Get FC connection topology out of f/w during startup. Reset restriction
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=9eb2fa412801eac66a0ecc11fdf696d4d1f8f950;p=openbsd

Get FC connection topology out of f/w during startup. Reset restriction
against targets < 129 if we're on a Public Loop- we can have those, yes.
Fix all the settings isp_sendmarker all throughout this file to OR in
the bus that we are trying to synchronize (e.g., after a bus reset)- this
way we don't wipe out pending sendmarker settings that haven't been done
yet.
