As the alignment of 64bit platforms may be defferent from 32bit one,
should it be like the following?

IW_EV_LCP_LEN is the same on both 32-bit and 64-bit platforms, it is
just the size of the "len" and "cmd" portions of struct iw_event.

Those are both __u16, so IW_EV_LCP_LEN always evaluates to "4",
try it if you do not believe me. :-)

The iwreq_data size is invariant across the calculations.
If it's bigger on 64-bit, more will be subtracted in the
calculation performed by IW_EV_LCP_LEN.

So my patches are correct as-is and we do not need to
be mindful of compat'ness wrt. IW_EV_LCP_LEN.
