Revision e13ad1443684f7afaff24cf207e85e97885256bd authored by Manish Chopra on 23 February 2022, 08:57:20 UTC, committed by Jakub Kicinski on 24 February 2022, 17:06:18 UTC
Commit b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") added new firmware support in the driver with maintaining older firmware compatibility. However, older firmware was not added in MODULE_FIRMWARE() which caused missing firmware files in initrd image leading to driver load failure from initrd. This patch adds MODULE_FIRMWARE() for older firmware version to have firmware files included in initrd.
