Subject: [dpdk-dev]  [PATCH V1] testpmd: add eeprom/module eeprom display
Date: Tue,  1 Sep 2020 14:56:54 -0400
Message-ID: <20200901185654.76346-1-dliu@iol.unh.edu> (raw)

Add EEPROM dump command
  "show port <port_id> eeprom"
Add module EEPROM dump command
     "show port <port_id> module_eeprom"
Commands will dump the content of the 
EEPROM/module EEPROM for the selected port.
