| H A D | if_urtwvar.h | diff 198194 Sat Oct 17 22:17:42 MDT 2009 weongyo overhauls urtw(4) for supporting RTL8187B devices properly that there was major changes to initialize RF chipset and set H/W registers and removed a lot of magic numbers on code. Details are as follows: - uses the endpoint 0x89 to get TX status information which used to get TX complete or retry numbers or get a beacon interrupt. It's only valuable for RTL8187B. - removes urtw_write[8|16|32]_i functions that it's useless now. - uses ic->ic_updateslot to set SLOT, SIFS, DIES, EIFS, CW_VAL registers that doesn't set these whenever the channel is changed. - code for initializing RF chipset for RTL8187B changed a lot that there was many problems on TX transfers so it doesn't work properly even if just for a ping/pong. Now it becomes more stable than before that TX throughputs using netperf(1) were about 15 ~ 17Mbps/s though sometimes it encounters packet losses. - removes a lot of magic numbers that in the previous all of representing RX and TX descriptors were consisted of magic numbers and structures. It'd be more readable rather than before. - calculates TX duration more accurately for urtw(4) devices. - style(9) |
