Subject: bnxt_en: Retrieve the hardware bridge mode from the firmware.
X-Git-Tag: v5.15~10516^2~448^2~8
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=32e8239c9138a050bc1feeea7cf41f27d79e6664;p=mirror_ubuntu-kernels.git

bnxt_en: Retrieve the hardware bridge mode from the firmware.

Retrieve and store the hardware bridge mode, so that we can implement
ndo_bridge_{get|set)link methods in the next patch.
