wi hostap fix, kind of
I spent a few hours tinkering (tampering?) with this driver, and have a fix.
I've verified that it works: my download speed went up from 170
kbytes/sec to 470 kbytes/sec, which is what I'd expect on an 11Mbps
network.
If anyone's interested, here it is:
The Intersil manual on page 4-28 says that transmit packets need to have their TxRate field filled in with 10,20,55 or 110, depending on the transmission speed.
The 4.X driver sets the field tx_frame.wi_tx_rate in function wihap_check_tx(), called from wi_start().
The 5.X driver calls this field frmhdr.wi_tx_rate, and leaves it zero.
If you want to run at 11MBps, add a line
frmhdr.wi_tx_rate = 110;
in wi_start(), just before the call to wi_write_bap().
(Obviously, this is just a cheesy hack. The real code would have to find the actual tx rate. I just want to point out where the problem lies).
