The branch main has been updated by ssaxena: URL: https://cgit.FreeBSD.org/src/commit/?id=b7d6334df61a559e98191f90fd5e611e0d077def commit b7d6334df61a559e98191f90fd5e611e0d077def Author: Sreekanth Reddy <sreekanth.reddy@broadcom.com> AuthorDate: 2026-01-23 16:36:02 +0000 Commit: Sumit Saxena <ssaxena@FreeBSD.org> CommitDate: 2026-01-27 12:12:23 +0000 bnxt_re: Fix active_speed value when two ports are aggregated Currently driver is not considering the active_lanes while displaying the speed & width of port and hence it showing invalid active_speed and active_width values in the ibv_devinfo command output when two ports are aggregated at hardware level. Fixed the driver to consider the active_lanes while determining the active_speed & active_width values.
