[PATCH net 1/4] bnxt_en: read EEPROM A2h address using page 0
From: Michael Chan <michael.chan@broadcom.com>
Date: 2020-11-16 00:28:32
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: Edwin Peer <redacted>
The module eeprom address range returned by bnxt_get_module_eeprom()
should be 256 bytes of A0h address space, the lower half of the A2h
address space, and page 0 for the upper half of the A2h address space.
Fix the firmware call by passing page_number 0 for the A2h slave address
space.
Fixes: 42ee18fe4ca2 ("bnxt_en: Add Support for ETHTOOL_GMODULEINFO and ETHTOOL_GMODULEEEPRO")
