ice(4): Update to 1.34.2-k

- Adds FW logging support
  - Once enabled, this lets the firmware print event and error messages
    to the log, increasing the visibility into what the hardware is
    doing; this is useful for debugging
- General bug fixes
- Adds inital DCB support to the driver
  - Notably, this adds support for DCBX to the driver; now with the
    fw_lldp sysctl set to 1, the driver and adapter will adopt a DCBX
    configuration sent from a link partner
  - Adds statistcs sysctls for priority flow control frames
  - Adds new configuration sysctls for DCB-related features: (VLAN) user
    priority to TC mapping; ETS bandwidth allocation; priority flow
    control
- Remove unused SR-IOV files (until support gets added)
