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