The isp(4) driver (and ispfw(4) firmware) previously only included firmware for Qlogic controllers up to 8Gb. It recently gained firmware for the 27XX and 28XX series controllers along with improved firmware loading capabilities. The 9.x firmware available for the 27XX and 28XX controllers in ispfw(4) adds login state for NVMe devices in the top nibble of the login state in the port database (isp_pdb_24xx_t in ispmbox.h). This breaks the check at the end of isp_getpdb() to make sure the device is in the right login state. As a result, it breaks device discovery for many (perhaps all?) FC devices. In my testing with IBM LTO-6 drives attached to a quad port 16Gb Qlogic 2714, they don't show up when they are directly connected (and in loop mode) or connected via a switch (and in fabric mode). So, mask off the top bits of of the login state before checking it. This shouldn't break anything, because all of the existing login states defined in ispmbox.h are in the low nibble. sys/dev/isp/ispmbox.h: Add a FCP login state mask define, and a NVMe login state shift. sys/dev/isp/isp.c: In isp_getpdb(), make sure we're only looking at the FCP login state bits when we try to determine whether a device is in the right login state.
