8 glm Legacy Symbios/NCR SCSI
From the http://cr.opensolaris.org/~gdamore/openi18n/TODO.html list
9 ncrs Legacy Symbios/NCR SCSI (EOF? Merge with glm?)
Well, glm and ncrs are closed source, so after this PSARC the merge will not happen. Of course, you can try to replace the whole stuff with some xBSD driver if there is such.
24 bnx Broadcom 10GbE
25 bnxe Broadcom 10GbE (not sure the difference)
bnx is 1Gb, bnxe is 10Gb
For the most of the drivers you would need to speak with HW companies. Some of them are distributing these drivers from their websites, but as closed source, of course.
Or search for xBSDs replacements.
