87656821dc ifconfig(8): Display extended compliance code string for SFP transceivers
- Updates tables in affected files with new entries from newer spec
revisions of SFF-8472, SFF-8024, and SFF-8636

- Change ifconfig to read and display the extended compliance code for
SFP media if the extended compliance code is not 0. This was being displayed
for QSFP transceivers only, but SFP28 media uses this to report 25G
capability.

6c29569229 Improve detection of extended QSFP diagnostics.
The standards in the QSFP diagnostics area are not clear when the
additional measurements are present or not. Use a valid temperature
reading as an indicator for the presence of voltage and TX/RX power
measurements.

78a71b3a33 Simplify i2c reader: we don't need per-NIC handler anymore.
Make code use read_i2c() function instead of callback.
Simplify&document struct i2c_info.
Consistently use uint8_t to read from i2c.

0db31aaac8 * 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.

69a7dea554 * 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.

81b97334ef * 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.
