Lots of fun:
With the latest git (2.6.25-02519-g3925e6f) madwifi will not install due
to an undefined reference to ieee8021_power.c {{{__skb_append}}} line 247.
After looking in skbuff.h I’ve noticed that {{{__skb_append}}} was
{{{skb_append}}}. So to install madwifi you need to change
madwifi/net80211/ieee8021_power.c line 247 from {{{__skb_append}}} to
{{{skb_append}}}.
It’s sort of like double clicking setup.exe and then next/next/next/finish only a lot more interesting.
