New Revision: 270064
URL: http://svnweb.freebsd.org/changeset/base/270064
Log:
Add support for reading i2c SFP/SFP+ data from NIC driver and
presenting most interesting fields via ifconfig -v.
This version supports Intel ixgbe driver only.
Tested on: Cisco,Intel,Mellanox,ModuleTech,Molex transceivers
MFC after: 2 weeks
