[SCSI] fcoe, libfcoe: Add support for FIP. FCoE discovery and keep-alive.
FIP is the new standard way to discover Fibre-Channel Forwarders (FCFs)
by sending solicitations and listening for advertisements from FCFs.
It also provides for keep-alives and period advertisements so that both
parties know they have connectivity. If the FCF loses connectivity to
the storage fabric, it can send a Link Reset to inform the E_node.
This version is also compatible with pre-FIP implementations, so no
configured selection between FIP mode and non-FIP mode is required.
We wait a couple seconds after sending the initial solicitation
and then send an old-style FLOGI. If we receive any FIP frames,
we use FIP only mode. If the old FLOGI receives a response,
we disable FIP mode. After every reset or link up, this
determination is repeated.
