The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-07-03T15:56:45Z Alexander Motin mav@FreeBSD.org 2017-07-03T15:56:45Z urn:sha1:a94fab67bb9c07d5837c9e2ad25d48b9b701643a Instead of using GID_FT SNS request to get list of registered FCP ports, use GID_PT to get list of all Nx_Ports, and then use GFF_ID and/or GFT_ID requests to find whether they are FCP and target capable. The problem with old approach is that GID_FT does not report ports without FC-4 type registered. In particular it was impossible to boot OS from FreeBSD FC target using QLogic FC BIOS, since one does not register FC-4 type even on new cards and so ignored by old code as incompatible. As a side bonus this allows initiator to skip pointless logins to other initiators by fetching that information from SNS instead. In case some switches do not implement GFF_ID/GFT_ID correctly, add sysctls to disable that functionality. I handled broken GFF_ID of my Brocade 200E, but there may be other switches with different bugs. Linux also uses GID_PT, but GFF_ID is disabled by default there, and GFT_ID is not supported.

Also it removes DMA resources allocation for hardcoded number of requests before fetching the real number from firmware. Also it prepares ground for more flexible IRQs allocation according to firmware capabilities.

It would be good to use target name from CTL here instead of hostname, but it is not passed here through CAM now.

It required exclusive use of scratch space of driver and mailbox registers of the hardware. Because of that shared resources use this code could not really sleep, having to spin for completion, blocking any other operation. This change introduces new asynchronous design, sending the IOCBs directly on request queue and gracefully waiting for their return on response queue. Returned IOCBs are identified with unified handle space from r292725.
