Hi, > Is there any way to get rt61 to report the receive timestamp? That would > be very useful for monitor mode and good for IBSS. The specsheets say nothing about TSF timestamps anywhere else then the registers (which is accessed by the get_tsf() callback function). To be more exact, the specsheets say _nothing_ about the RXD descriptors at all, which means they are not helpful for that. ;) However there are a few RXD fields which are labeled as "reserved" which could mean the field is present, just not documented. You could try printing the values of those words to see if they contain valid data, and to be more exact the TSF data (this can be done in the function rt61pci_fill_rxdone(...)) The undocumented/reserved words are: 6 to 15 Do you want me to come up with a patch for this? Note that these undocumented fields only are present in rt2500pci and rt61pci. Neither rt2500usb or rt73usb contain them, which means that they can't report the TSF based on descriptor information.
