* Add new net/sff8436.h containing constants used to access
QSFP+ data via i2c inteface. These constants has been taken
from SFF-8436 "QSFP+ 10 Gbs 4X PLUGGABLE TRANSCEIVER" standard
rev 4.8.
* Add support for printing QSFP+ information from 40G NICs
such as Chelsio T5.
This commit does not contain ioctl changes necessary for this
functionality work, there will be another commit soon.
Example:
