            Bug ID: 219683
           Summary: Since r318216 iwm firmware loading aborts with
                    "unknown firmware section 512"
           Product: Base System
           Version: CURRENT
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: wireless
          Assignee: freebsd-wireless at FreeBSD.org
          Reporter: iz-rpi03 at hs-karlsruhe.de

After changing the wireless card in a laptop running 32 bit FreeBSD 12.0 into
a Intel 7260 I get a firmware loading error.

The kernel messages are
# kldload if_iwm
iwm0: <Intel(R) Dual Band Wireless AC 7260> mem 0xf69fe000-0xf69fffff irq 17 at
device 0.0 on pci1
iwm0: iwm_read_firmware: unknown firmware section 512, abort
iwm0: firmware parse error 22, section type 512
iwm0: iwm_read_firmware: failed 22
iwm0: Failed to start INIT ucode: 22
#

Using the older, 16th, version of the firmware causes the same error message.
So I think it is not firmware version related.

Going back to r318215 fixes the firmware loading, while with r318216 the error
shows up.
The r318216 log message is related to iwm's firmware handling:

[iwm] Sync iwm_read_firmware()'s loop to iwlwifi's code.
Obtained from:  dragonflybsd.git d1c10ccfcf2d6d2a664f17197add0b4f93333181
