The FC-BB-6 committee is proposing a new FIP usage model called
VN_port to VN_port mode. It allows VN_ports to discover each other
over a loss-free L2 Ethernet without any FCF or Fibre-channel fabric
services. This is point-to-multipoint. There is also a variant
of this called point-to-point which provides for making sure there
is just one pair of ports operating over the Ethernet fabric.
This patch defines the new message type and subtypes as well as
one new descriptor type used by VN2VN mode.
These are all still at the proposed stage and subject to change.

When the D bit is set if the FKA_ADV_Period of the FIP Discovery
Advertisement, the ENode should not transmit period ENode FIP Keep Alive and
VN_Port FIP Keep Alive (FC-BB-5 Rev2, 7.8.3.13).
Note that fcf->flags is taken directly from the fip_header, I am claiming one
bit for the purpose of the FIP_FKA_Period D bit as FIP_FL_FK_ADV_B, and use
FIP_HEADER_FLAGS as bitmask for bits used in fip_header.

FIP is the FCoE Initialization Protocol and this patch
adds the protocol ethertype to the kernel's list of
ethertypes.
