>Description:
I've updated my aironet firmware and it cannot be attached anymore:

Aug 17 18:01:50 mubutu /netbsd: an0 at pcmcia0 function 0: <Cisco Systems, 350 Series Wireless LAN Adapter>
Aug 17 18:01:52 mubutu /netbsd: an0: record buffer is too small, rid=ff00, size=198, len=258
Aug 17 18:01:52 mubutu /netbsd: an0: read caps failed
Aug 17 18:01:52 mubutu /netbsd: an0: failed to attach controller
Aug 17 18:22:26 mubutu /netbsd: an0 detached

I've made a quick (dirty?) patch to anreg.h so the struct an_softc member sc_caps is as big as requested in an_attach().
>How-To-Repeat:
Update the firmware for your aironet pcmcia card.
