Subject: [PATCH 034/146] iwlwifi: pcie: support dumping FH in a000 hw
Git-commit: 723b45e24150f1b9bde5c1f51f1a845982cb4eeb
Patch-mainline: v4.13-rc1
References: FATE#322675
FH in A000 HW are placed in a different location,
and need to be read as prph, rather than direct.
Support A000 dumping as well as legacy.
