Hi folks As mentioned in the subject, kernel-3.18.12-11 is missing firmware files required to run Broadcom/Qlogic network cards, driven by bnx2x driver. While in the source-rpm, there is a bnx2/bnx2x firmware tgz being applied during the rpm build, along with a patch adding these firmware files to firmware/Makefile, neither the tgz nor the patch contain the required firmware files. In 3.18, the driver bumped to version 1.710.51-0, requiring the following firmware files/versions to work: firmware: bnx2x/bnx2x-e2-7.10.51.0.fw firmware: bnx2x/bnx2x-e1h-7.10.51.0.fw firmware: bnx2x/bnx2x-e1-7.10.51.0.fw I helped myself by either copying the required firmware-files to the target-machines' /lib/firmware/bnx2x dir and ultimately by adding the files to the source-rpm along with a new Makefile patch and rebuilding the kernel rpms. However, as bnx2x NICs seem quite commonplace these days, I suggest to fix this 'upstream'. If required, I can provide the (trivial) patch. I pulled the firmware-files from a CentOS 7 stock kernel.
