| H A D | if_stereg.h | diff 200913 Wed Dec 23 17:51:07 MST 2009 yongari We don't need to generate DMA complete interrupt for every transmitted frames. So request interrupt for every 16th frames. Due to the limitation of hardware we can't suppress the interrupt as driver should have to check TX status register. The TX status register can store up to 31 TX status so driver can't send more than 31 frames without reading TX status register. With this change controller would not generate TX completion interrupt for every frame, so reclaim transmitted frames in ste_tick(). |
