Subject: [PATCH net-next v2 0/6] ice: lower CPU usage with GNSS

This series lowers the CPU usage of the ice driver when using its
provided /dev/gnss*.

v2:
 - Changed subject of patch 1. Requested by Andrew Lunn.
 - Added patch 2 to change the polling interval as recommended by Intel.
 - Added patch 3 to remove sq_cmd_timeout as suggested by Simon Horman.

Michal Schmidt (6):
  ice: do not busy-wait to read GNSS data
  ice: increase the GNSS data polling interval to 20 ms
  ice: remove ice_ctl_q_info::sq_cmd_timeout
  ice: sleep, don't busy-wait, for ICE_CTL_Q_SQ_CMD_TIMEOUT
  ice: remove unused buffer copy code in ice_sq_send_cmd_retry()
  ice: sleep, don't busy-wait, in the SQ send retry loop
