[PATCH net-next 06/11] bnxt_en: Add fw log trace support for 5731X/5741X chips
From: Michael Chan <michael.chan@broadcom.com>
Date: 2025-09-15 03:05:59
Subsystem:
broadcom bnxt_en 50 gigabit ethernet driver, networking drivers, the rest · Maintainers:
Michael Chan, Pavan Chebbi, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Shruti Parab <redacted> These older chips now support the fw log traces via backing store qcaps_v2. No other backing store memory types are supported besides the fw trace types.
