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

Michal Schmidt says:

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

The following are changes since commit e315e7b83a22043bffee450437d7089ef373cbf6:
  net: libwx: fix memory leak in wx_setup_rx_resources
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE

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
