This commit ensures that the bnxt_re module is automatically loaded whenever bnxt_en is loaded by StarlingX's boot-up process or manually by the user. The bnxt_re module is not automatically loaded, and this requires manually loading the module before being able to use RDMA. In contrast, bnxt_en has aliases that allows it to be automatically loaded on systems with compatible Broadcom network adapters. This commit adds a 'softdep' modprobe hook for bnxt_en, so that the bnxt_re module is automatically loaded after the bnxt_en module is loaded. In terms of alternatives, the following options were considered: - Always load bnxt_en and bnxt_re, like Mellanox OFED's drivers. This option's main drawback is that the modules will always consume resources such as kernel memory, even when a compatible network adapter is not available. - Use install and remove hooks. This option is functionally similar to having a softdep hook, but allows the use of arbitrary shell commands. We did not opt for this option, because the modprobe.conf manual page mentions that the install/remove hooks will eventually be deprecated. Verification - An ISO image was built successfully using a monolithic incremental build procedure. - The built ISO image was installed onto a virtual machine in All-in-One simplex mode, low-latency profile. - The bnxt_en module was loaded using "sudo modprobe bnxt_en". "lsmod" showed that both bnxt_en and bnxt_re were loaded. - The bnxt_en module was removed using "sudo modprobe -v -r bnxt_en", which indicated that bnxt_re and bnxt_en were removed, in that order. The end result was confirmed with "lsmod". Story: 2009915 Task: 44917 Change-Id: I6f58ed7b1cd07d856ae9fba5f27820adf8f649d0 Signed-off-by: M. Vefa Bicakci <vefa.bicakci@windriver.com>
