* [SCSI] libfcoe: add protocol description of FIP VN2VN modeJoe Eykholt2010-07-281-3/+43
| | | | | | | | | | | | | | | | | | 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.

* [SCSI] libfcoe: add checking disable flag in FIP_FKA_ADVYi Zou2009-12-041-1/+11
| | | | | | | | | | | | | | 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.
