From: David Marchand Date: Wed, 7 Jul 2021 12:08:17 +0000 (+0200) Subject: net/ice: factorize firmware loading X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7f7cbf80bdb7b57f3f67fe244be4572efa69b374;p=dpdk.git net/ice: factorize firmware loading Both "normal" and "dcf" inits have their copy of some firmware loading code. The DSN query is moved in specific parts for the "normal" and "dcf" init. A common helper ice_load_pkg is then introduced and takes an adapter pointer as its main input. This helper takes care of finding the right firmware file and loading it. The adapter active_pkg_type field is set by this helper. The ice_access macro is removed from the osdep.h header: osdep.h should only hosts wrappers for base driver code.
