The problem with having icmp_bsd_compat as an ndd tunable is
that we now need to have *all* apps running in bsd compat mode,
or all apps running in the non-compat mode.
I guess you are going to add a new option for an app
to override this. Right? This is good :-)
I don't think "interesting alignment" is something we should
throw on the admin's shoulder to figure out.
Actually, it is probably not the sys admin who may be
interested in this. There are third parties who
configure a Solaris machine to do specific things and
ship the configured machine to customers. And customers
just use the machine as is. So I am wondering if this
is useful to those third party vendors.
But what I was
thinking was to have the *_wroff_extra set to the larger
of (32, ill_phys_addr_length) with the appropriate rounding
off to the beat alignment boundary.
