Subject: [PATCH 4/7] ethtool: Fix SFF 8079 cable technology bit parsing
|
||
|
|
|
||
|
|
According to the transceiver compliance code definition in the spec, bits
|
||
|
|
2 & 3 in the 8th byte are indication of active/passive cable, and not
|
||
|
|
specifically related to FC/copper.
|
||
|
|
|
||
|
|
Fixes: 2edf56749abe ("ethtool: Addition of -m option to dump module eeprom")
