From 0e1a2a3e6e7d37cea9f8586f6d7745b539147d9f Mon Sep 17 00:00:00 2001 From: Erez Alfasi Date: Tue, 5 Mar 2019 15:42:23 +0200 Subject: ethtool: Add SFF-8436 and SFF-8636 max EEPROM length definitions Added max EEPROM length defines for ethtool usage: #define ETH_MODULE_SFF_8636_MAX_LEN 640 #define ETH_MODULE_SFF_8436_MAX_LEN 640 These definitions are used to determine the EEPROM data length when reading high eeprom pages. For example, SFF-8636 EEPROM data from page 03h needs to be stored at data[512] - data[639].
