ice(4): Update to 1.37.7-k 
Notable changes include:

- DSCP QoS Support (leveraging support added in
  rG9c950139051298831ce19d01ea5fb33ec6ea7f89)
- Improved PFC handling and TC queue assignments (now all remaining
  queues are assigned to TC 0 when more than one TC is enabled and the
  number of available queues does not evenly divide between them)
- Support for dumping the internal FW state for additional debugging by
  Intel support
- Support for allowing "No FEC" to be a valid state for the LESM to
  negotiate when using non-standard compliant modules

Also includes various bug fixes and smaller enhancements, too.
