* Fix a couple of problems that may make gem(4) get stuck:kettenis2008-08-261-67/+91
| | | | | | | | | | | | | | | | | | | 1. If bus_dmamap_load_mbuf() fails because there are not enough segments in the map, defrag the mbuf. 2. If there are not enough free (hardware ring) descriptors, set IFF_OACTIVE and keep the packet on the queue. 3. If there is some other resource starvation that makes bus_dmamap_load_mbuf() or defragmentation fail, drop the packet. Don't set IFF_OACTIVE, since the Tx ring could be empty and we'd be stuck. 4. Only pass packets that are actually handed off to the hardware to BPF. Do so before handing them off to the hardware to make sure the packet isn't freed behind our back. ok dlg@

* The gem driver will sometimes unmap bus_dma mappings that are stillhenric2003-03-021-4/+3
| | | | | | | | | in use by the hardware. Since the sparc64 has IOMMUs, an access by the hardware after the unmap operation will cause a fault. This replaces "disable" calls by "reset" calls. This increases the time between the command to disable DMA and when the maps are actually unloaded.
* - Either memset() or loop and set to zero, not bothjason2003-01-231-8/+13
| | | | | | - reading RX_COMPLETION is a waste of time (and a -slow- PCI read vs. an, albeit uncached, memory access to determine the same thing). - on RX_OVERFLOW, reset the board; the RX unit has probably wedged

* - Fix one typo (instead of two disable_rx, one disable_rx and one disable_tx)art2002-08-281-3/+3
| | | | | | | | - Instead of setting OACTIVE on the interface when encap fails and never clearing it, set a 2 second timer instead and hope that the memory situation will improve. This stops the lockups of the interface when memory is running low. jason@ ok.
