ethernet: T3163: only change ring-buffer settings if required
Only update the RX/TX ring-buffer settings if they are different from the ones
currently programmed to the hardware. There is no need to write the same value
to the hardware again - this could cause traffic disruption on some NICs.
(cherry picked from commit 29082959e0efc02462fba8560d6726096e8743e9)
