Subject: ice: Add support for VF rate limiting
Patch-mainline: v5.16-rc1
Git-commit: 4ecc8633056b8d2f214c6ce860a50837e5c8fb41
References: jsc#SLE-18375
Implement ndo_set_vf_rate to support setting of min_tx_rate and
max_tx_rate; set the appropriate bandwidth in the scheduler for the
node representing the specified VF VSI.
