Applied to target-arm.next, thanks, with the commit message
tweaked to:

    hw/net/npcm_gmac: Change error log to trace event

    Convert the LOG_GUEST_ERROR for the "tx descriptor is owned
    by software" to a trace message. This condition is normal
    when there is there is nothing to transmit, and we would
    otherwise spam the logs with it in that situation.
