SVN rev 199666 on 2009-11-22 19:44:11Z by yongari
Rearrange bge_start_locked to see we can send more frames by
checking IFF_DRV_RUNNING and IFF_DRV_OACTIVE flags. Also if we
have less than 16 free send BDs set IFF_DRV_OACTIVE and try it
later. Previously bge(4) used to reserve 16 free send BDs after
loading dma maps but hardware just need one reserved send BD. If
prouder index has the same value of consumer index it means the Tx
queue is empty.
While I'm here check IFQ_DRV_IS_EMPTY first to save one lock
operation.
