| Subject: bnxt_en: read EEPROM A2h address using page 0 |
| |
| From: Edwin Peer <edwin.peer@broadcom.com> |
| |
| [ Upstream commit 4260330b32b14330cfe427d568ac5f5b29b5be3d ] |
| |
| 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") |
