5c02a66b2b * Unconditionally turn on SIOCGI2C probing for all interfaces
on "ifconfig -v". I've seen no measurable timing difference
    for doing additional SIOCGI2C call for system with 4k vlans.
* Determine appropriate handler (SFP/QSFP) by reading identification
    byte (which is the same for both SFF-8472 and SFF-8436) instead
   of checking driver name.

ea463f2dc0 * Add SIOCGI2C driver ioctl used to retrieve i2c info.
* Convert ixgbe to use this ioctl
* Convert ifconfig to use generic i2c handler for  "ix" interfaces.

c59adfc6a5 * 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.
