Eric Joyner 7d7af7f85b ice(4): Update to 0.26.16
Summary of changes:

- Assorted bug fixes
- Support for newer versions of the device firmware
- Suspend/resume support
- Support for Lenient Link Mode for E82X devices (e.g. can try to link with
  SFP/QSFP modules with bad EEPROMs)
- Adds port-level rx_discards sysctl, similar to ixl(4)'s

This version of the driver is intended to be used with DDP package 1.3.16.0,
which has already been updated in a previous commit.
