Hi All, mac80211/scan.c uses a NULL frame with IEEE80211_FCTL_PM to switches between active and powersave mode. I'm test this feature with b43 driver.
However, in the outgoing packets captured by kismet, I found that IEEE80211_FCTL_PM is always 0, NOT 1. To narrow down the scope for debugging, I printed out the frame_control of outgoing frames in b43_dma_tx, right before the packets is sent via DMA. As expected, the printout shows that IEEE80211_FCTL_PM is set correctly (0x48 0x11). Does this mean that firmware/hardware is changing the IEEE80211_FCTL_PM bit later by itself? If that's the case, do I need to send some additional control flags to firmware/hardware to avoid that? Thank you for your time, Jun _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
