| H A D | if_bgereg.h | diff 226807 Wed Oct 26 18:44:55 MDT 2011 yongari BCM5719 cannot handle DMA requests for DMA segments that have larger than 4KB in size. However the maximum DMA segment size created in DMA tag is 4KB, so we wouldn't encounter the issue here. Just record this issue such that let developers not to create a DMA segment that is larger than 4KB for BCM5719. It's possible to split a DMA segment into multiple smaller ones in run time but I believe it's not worth to implement that. |
