Re: Rate information in ad-hoc and mesh mode

[Charles Gordon <digigordo@gmail.com>]

I am using version 2.6.28 of the kernel.  We are using our own
wireless driver.  However, the problem does not appear to be in the
driver.  The iw utility uses the SIOCGIWRATE ioctl to get rate
information.  This ioctl is handled by the ieee80211_ioctl_giwrate
function in net/mac80211/wext.c in the 2.6.28 version of the kernel.
This function returns immediately if sdata->vif.type !=
NL80211_IFTYPE_STATION, which will be the case for ad-hoc mode.
