Subject: [PATCH 3/3] net: stmmac: Time Based Scheduling support for OF platforms

This allows enabling TBS for TX queues by adding the
snps,time-based-scheduling property. You should check for support for this
on your particular controller before enabling. Typically, TX queue 0 does
not support TBS.
