X-Git-Tag: v2.6.30-rc1~185^2~25 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=97c8389d54b9665c38105ea72a428a44b97ff2f6;p=pandora-kernel.git [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.
