Marek Behún 7b31c2e9ed kernel: Backport mvneta crash fix to 5.15
Backport Russell King's series [1]
  net: mvneta: reduce size of TSO header allocation
to pending-5.15 to fix random crashes on Turris Omnia.

This also backports two patches that are dependencies to this series:
  net: mvneta: Delete unused variable
  net: mvneta: fix potential double-frees in mvneta_txq_sw_deinit()

Subject: net: mvneta: Use struct tc_mqprio_qopt_offload for MQPrio
configuration
The struct tc_mqprio_qopt_offload is a container for struct tc_mqprio_qopt,
that allows passing extra parameters, such as traffic shaping. This commit
converts the current mqprio code to that new struct.
