Subject: [PATCH net-next 4/7] ethtool: Document behavior when module EEPROM bank attribute is omitted

From: Ido Schimmel <idosch@...dia.com>

The kernel assumes bank 0 when 'ETHTOOL_MSG_MODULE_EEPROM_GET' is sent
without 'ETHTOOL_A_MODULE_EEPROM_BANK'.

Document it as part of the interface documentation.
