Subject: [PATCH 29/35] cmis: Initialize Page 02h in memory map
|
|
|
2a1b01 |
|
|
|
2a1b01 |
Page 02h stores module and lane thresholds that are going to be parsed
|
|
|
2a1b01 |
and displayed in subsequent patches.
|
|
|
2a1b01 |
|
|
|
2a1b01 |
Request it via the 'MODULE_EEPROM_GET' netlink message and initialize it
|
|
|
2a1b01 |
in the memory map.
