[ipxe-devel] [PATCH 1/1] [iscsi] don't close when receiving nop-in

[Vishvananda Ishaya Abrams]

Some iscsi targets send nop-in. Rather than closing the connection when
we receive one, it is more user friendly to log a debug message and
keep the connection open. Eventually, it would be nice if ipxe
supported replying to nop-ins, but we might as well keep the connection
open until the initiator disconnects us.
