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
* 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.
Example: cxl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,.....> ether 00:07:43:28:ad:08 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet 40Gbase-LR4 <full-duplex> status: active plugged: QSFP+ 40GBASE-LR4 (MPO Parallel Optic) vendor: OEM PN: OP-QSFP-40G-LR4 SN: 20140318001 DATE: 2014-03-18 module temperature: 64.06 C voltage: 3.26 Volts lane 1: RX: 0.47 mW (-3.21 dBm) TX: 2.78 mW (4.46 dBm) lane 2: RX: 0.20 mW (-6.94 dBm) TX: 2.80 mW (4.47 dBm) lane 3: RX: 0.18 mW (-7.38 dBm) TX: 2.79 mW (4.47 dBm) lane 4: RX: 0.90 mW (-0.45 dBm) TX: 2.80 mW (4.48 dBm)
Tested on: Chelsio T5 Tested on: Mellanox/Huawei passive/active cables/transceivers.

MFC r258692 (gnn).
Add constants for use in interrogating various fiber and copper connectors most often used with network interfaces.
The SFF-8472 standard defines the information that can be retrieved from an optic or a copper cable plugged into a NIC, most often referred to as SFP+. Examples of values that can be read include the cable vendor's name, part number, date of manufacture as well as running data such as temperature, voltage and tx and rx power.
Copious comments on how to use these values with an I2C interface are given in the header file itself.
